that's a truck so it needs a truckburetor, not a carburetor

[–] RememberTheApollo_@lemmy.world 2 points 2 hours ago

Or your points are shot because of that cam you stuffed in the engine and then decided to not go with electronic ignition.

[–] Ariselas@piefed.ca 12 points 9 hours ago

Dude, I can fix that for you. Trust me, it's supposed to idle at 3000RPM!

[–] BeUnique@lemmy.zip 36 points 16 hours ago (7 children)

I just got a car that shuts off when stopped. I hate it. Especially when you stop at a stop sign for a second too long and it shuts off then you hit the gas and it hesitates because it has to literally start the engine before moving.

[–] 1984@lemmy.today 1 points 2 hours ago* (last edited 2 hours ago)

I think its just a bad car. I have a volvo xc40 and it starts right away and takes off in less than a second. No hesitation. It's a fuel car, not electric.

[–] ftbd@feddit.org 4 points 7 hours ago (2 children)

Every car I've ever driven with such a feature only shuts off when in neutral and you let go of the clutch. For short stops, I just stay in first gear and keep the clutch pressed.

[–] 1984@lemmy.today 1 points 2 hours ago

I have an automatic and it shuts off when I just brake until it stops. Then I just release the brake and it starts. Very easy.

[–] i_am_hiding@aussie.zone 1 points 5 hours ago

Same, but I'm the only person I know who still drives manual cars.

[–] blargh513@sh.itjust.works 10 points 11 hours ago (3 children)

I have been renting a lot of cars lately. The hybrids do the best job because hybrid. The gas cars can be hit or miss. A jeep renegade I rented did ok except that sometimes it would auto stop, sometimes it wouldn't. You had to be stopped and the. Push the brake a little harder to engage.

I have a Volvo and if you stop at a pace other than very gentle, it will shut off the engine before you've stopped moving. That one is annoying.

Got a newer Volvo as a loaner and the baby hybrid system in them is FAR better. You can't even really hear it start up. I believe it doesn't have a traditional starter, you hear almost nothing when you start it for the first time. It just kind of goes from being off to running without any sound or vibration. Very weird but kinda cool.

Each system is a little different, some are not very good, others you don't even notice.

[–] 1984@lemmy.today 1 points 2 hours ago* (last edited 2 hours ago)

I have that hybrid volvo and it's amazing, I never even think about it. It just works. If someone wants to test drive, it's an automatic xc40 with b4 engine.

[–] historicaldocuments@lemmy.world 1 points 8 hours ago

A jeep renegade I rented did ok

You must've gotten a good one.

[–] Aqarius@lemmy.world 1 points 8 hours ago

The starter in the mHEVs is about as powerful as the entire engine of the original Fiat 500. It entirely skips the *r-r-r-*revup of a normal engine start.

[–] Imgonnatrythis@sh.itjust.works 23 points 16 hours ago (2 children)

I haven't seen one where this can't be disabled as a setting. Assume you've checked? If not imagine someone has found a hack for this.

[–] Sonotsugipaa@lemmy.dbzer0.com 14 points 14 hours ago (2 children)

Some cars, like mine, only allow you to temporarily disable the start-stop system, and it turns on every time you (fully) start the engine.

In my car specifically, if you manually turn the system back on, for whatever reason you have to reach a minimum speed of 10km/h before it works.

[–] scytale@piefed.zip 4 points 12 hours ago (1 children)

My guess is because it has to check again if your car’s state meets all the requirements for it to engage. It takes a combination of factors for the car to allow start-stop to engage (engine temp, battery health, A/C, etc.), and if you just turned it on again after it was disabled, it need to get to a certain speed to be able to recalculate.

[–] Sonotsugipaa@lemmy.dbzer0.com 3 points 11 hours ago

It seems unnecessary, they could just have its user-set switch as one of those factors rather than forgetting everything upon disablng it.

[–] MML@sh.itjust.works 2 points 12 hours ago (1 children)

You can get a module that disables it, bad news is it's like $100, but if you've decently good with electronics you can diy one cheaper.

[–] Sonotsugipaa@lemmy.dbzer0.com 3 points 11 hours ago

At this point my muscle memory simply toggles it off as soon as the engine is on, occasionally I even manage to predict when I have to stop for more than 5 seconds and turn it on in time.

I bought a car in December that does this. Literally all you have to do is let off the brake wait half a second to 1 second and it starts right back up not a big deal. Just maybe you know have a slight bit of patience in your driving.

[–] TrickDacy@lemmy.world 2 points 11 hours ago (1 children)

That feature never affected my driving at all and never bothered me at all. In fact I don't think I ever remembered that it was a thing after the first week or two.

[–] froh42@lemmy.world 3 points 8 hours ago* (last edited 8 hours ago)

Depends very much on the car. My car has auto off and starts up the engine as soon as the car in front of me starts moving (it detects that with the parking and radar sensors).

Or if I just move the foot off the braking pedal the engine will be fully running as soon as my foot reaches the gas pedal.

It's at 2017 Mercedes, at the time they already spent some effort into that tech, for example I have an electrical water pump that keeps up the circulation even during auto off and the starter is different so it can start the car even while starting to move.

The only moment I turn it off (ok switch to sport mode which turns autostop off) is when I want to race someone at the light in order to change lanes in front of them later.

I normal operation you don't notice.

Ah and last year autostop did not work for a few months as my battery was old, the car noticed and refrained from stopping the engine until I got a new battery (It will also do if I need aircon or the motor is too cold or a number of other conditions)

[–] AoxoMoxoA@lemmy.world 2 points 12 hours ago (2 children)

I'm guessing they have a bunch of oil squirters engineered into the design but seems to me that constantly letting oil drain into the crank case while sitting then firing up again is going to cause a short life for these engines.

I've only riden in two vehicles that have this idiotic feature but they could both be disabled after the initial startup.

[–] froh42@lemmy.world 1 points 8 hours ago

Oil isn't the problem, my car will turn on again before too much oil drains out of the engine and oil pressure sinks too low. Cooling is, interstingly, so they switched to an electric water pump for cooling - it will stay running during auto off so you don't get too hot temperatures in the turbo for example. (4cyl 2l engine has a turbo)

There's quite a bit of tech going into auto off since it first appeared. (Heh, my first car in 1989 had an aftermarket start stop switch to stop the engine at the traffic light - i never used it except once or twice for fun - still one cylinder exploded one day on the Autobahn)

[–] blargh513@sh.itjust.works 2 points 11 hours ago (1 children)

Modern oils and modern cylinder lining makes this a non-issue.

You're more likely to have a modern car with bad rings as they chase fuel economy numbers. Honestly, a hybrid is a very solid choice anymore. Lifts the burden of the gas engine having to be hyper-efficient and eases the extreme tolerances required to get there.

Shame that there are very few fun hybrids, crazy expensive things don't count.

Infiniti made an m35h that actually had more power than the gas version and it got better mileage. Granted, it is a porky sedan, but that thing would still haul its fat ass.

[–] HeyThisIsntTheYMCA@lemmy.world 1 points 8 hours ago

We're defining fun very differently. My prius has ridiculous low end torque thanks to those electric motors.

[–] over_clox@lemmy.world 17 points 16 hours ago (2 children)

Smack the fuel tank half a dozen times with a sledge hammer, the fuel filter is probably clogged.

Can confirm, I just did this yesterday.

[–] blargh513@sh.itjust.works 3 points 11 hours ago (1 children)

Don't do this. If you unclog the filter the next stop for the junk you knocked loose is the engine.

Fuel filters are cheap and easy to replace.

[–] over_clox@lemmy.world 2 points 11 hours ago (2 children)

Fuel filter indeed is not cheap or easy to replace, not on a 96 Sonoma anyways. You either gotta drop the tank, or remove the pickup bed, to access the fuel pump, where the primary fuel sock filter is located.

Not easy or cheap to replace.

[–] Eat_Your_Paisley@lemmy.world 1 points 1 hour ago

There should be two filters, the sock on the fuel sending unit in the tank, and a real filter between the tank and the engine. If your pump and sock are 30 years old its time to get a loaded sending unit from AutoZone

[–] Crashumbc@lemmy.world 2 points 9 hours ago (1 children)

Nah fam, you just need a big hole saw! Permanent easy access through the bed :p

[–] HeyThisIsntTheYMCA@lemmy.world 1 points 8 hours ago

And makes your car go faster

[–] thallamabond@lemmy.world 6 points 15 hours ago (3 children)

Been a while, but this can also work on the starter. Just a suggestion, keep the hammer weight under 2lbs.

[–] Crashumbc@lemmy.world 3 points 9 hours ago

I had 82 Chevy Malibu station wagon in the early 90s while in college. The thing would start like a champion on the second turn, NEVER the first.

Which was fine except the contacts on the solenoid started sticking when it was below freezing. It would sit there and run the battery down unless you jumped out reached underneath with something heavy to knock the solenoid loose... Get back, now being the second try, it would immediately start like a champ...

Did that for 3 months before I finally changed the starter.

[–] rabidhamster@lemmy.dbzer0.com 2 points 10 hours ago (1 children)

Kept a hammer in the passenger footwell of my '89 Volvo wagon for exactly this reason.

No start? Pop the hood, and pop the starter.

[–] froh42@lemmy.world 3 points 8 hours ago

I feel knocking the starter with a hammer is a universal 80s driving experience. Like changing the electric distributor contacts mid trip, and using starter spray when the damn thing refuses to turn on again.

[–] baldingpudenda@lemmy.world 6 points 14 hours ago (1 children)

Preferably with a rubber head

[–] over_clox@lemmy.world 3 points 10 hours ago

Oh shit, 1000%!

You just reminded me that I have a rubber mallet, that needs to go in the truck..

[–] echodot@feddit.uk -3 points 7 hours ago* (last edited 7 hours ago) (2 children)

This is actually a myth. The engine requires way more fuel to start than it does to maintain running, I think the crossover point is around 8 minutes for most vehicles, so shutting the engine off at a stoplight absolutely does not save the environment. If anything it's actually worse for the environment by a tiny amount.

It's nothing to do with emissions, it's to reduce particulates around pedestrians.

[–] ShankShill@sh.itjust.works 4 points 5 hours ago

It's actually around 2-3 seconds worth of idle fuel to start.

8 minutes worth would surely hydro lock the engine.

[–] SomethingBurger@jlai.lu 1 points 5 hours ago* (last edited 5 hours ago) (1 children)

8 minutes at 50km/h is 6.6km. At 5L/100km, that's 0.3L.

You realise there is no way even the worst engine ever built uses that much fuel to start?

[–] UndergroundParking@lemmy.cafe 1 points 1 hour ago

Not the guy you're talking to, but this made me think!

I wonder if some 60s american 8 liter engine would actually consume that much. I think it's possible! Longer startup time, less efficient combustion...

[–] Mulligrubs@lemmy.world 2 points 12 hours ago (1 children)

I hate it, I will from now on be one of those guys in an old car. I hate those guys. God dammit

[–] Ariselas@piefed.ca 1 points 9 hours ago

go European and you can be one of those guys in an old car with mechanical fuel injection and you'll have a whole different set of problems.

[–] sibannac@lemmy.world 5 points 16 hours ago (3 children)

Does that actually do anything or is it planned obsolescence? I was under the impression turning off your engine and restarting at a stop wears the starter and it not worth the gas savings. Dealer service centers must be making bank if true.

[–] Imgonnatrythis@sh.itjust.works 15 points 16 hours ago (1 children)

I don't think that's true anymore with modern engines. It's my understanding that the on / off strain is no longer a limiting factor on engine wear and that the emissions and fuel saving benefits may be mild but are real from a net efficiency standpoint. While emissions savings are probably the greatest, I'm using this primarily to save anything I can with wartime gas prices.

[–] joelfromaus@aussie.zone 3 points 13 hours ago

Newer engines use different starter motor technology to reduce starter motor wear and the oil channels are designed to retain oil in the engine where previously there would be a moment of low pressure which you could hear as a slight tinny sound before oil flow.

Source: I’m no mechanic but I’ve dealt in parts for stop-start engines.

[–] Yoddel_Hickory@piefed.ca 7 points 15 hours ago (1 children)

Turning on and off increases wear in cars not designed for it. The cars that have the feature have beefy starters, it is a non-issue. And it does save a bit of gas and emissions at red lights, and stopped in traffic, and especially for assholes that leave the car on while their partner goes for a "quick" grocery run.

[–] zurohki@aussie.zone 3 points 13 hours ago

One of the nice things about EVs is being able to just run the aircon whenever I want, even in a closed garage. I charge on solar, the energy doesn't matter.
