Car Stalls When Comming To A Complete Stop

[Zeusimo]

Hey Everyone.

I Just Finished Making The 610 Drivable

Runs Good And Drives Like A Champ

 

But When Comming To A Complete Stop, It Stalls As If I Turned It Off

If I Slow Down Really Hard It Wants To Stall But Doesn't

To Stop I Have To Slow Down To Where I'm Bearly Rolling And Then Stop Completely

It Doesn't Do This When It's Idling

Just When I'm Comming To A Full Stop

I'm Kinda Confused... Idk

Is it an automatic? It's most common on automatics, but can happen with manuals too.

 

There are several things that cause this syptom, including:

* Vacuum leak

* Idle set too slow

* Idle stop (dashpot) is loose

* Idle mixture is incorrect

 

It's probably a vacuum leak. It could be at the distributor diaphragm, air cleaner motor, choke pull off or a cracked rubber hose. If you have a vacuum leak, you can compensate by adjusting the idle speed & mixture screws to get a good idle, but it still won't run exactly right -- often it will die when stopping.

It Idles At 800

It's A 5 Speed

I Don't Hear Any Leaks But It Is Missing The Choke And Air Cleaner

P.O. Threw Them Away...

You won't hear hissing with most vacuum leaks.

 

Even if the choke is missing, the choke pull off might still be there.

Clogged idle jet?

[ggzilla]

Possible, but that would like not allow it to idle well.

Disconnect the hose to the brake booster right at the manifold and plug it with duct tape or w/e. Try it now BUT: BE AWARE THE BRAKING PERFORMANCE WILL BE SEVERELY ALTERED REQUIRING MUCH MORE PEDDLE EFFORT. Try this only in a safe place.s

 

This is just a test to see if the hose or brake booster is the source of the vacuum leak.

duct tape or w/e?

[datzenmike]

What/ever. Just plug it up so it don't leak. :)

I didn't think anybody came to a complete stop in California..

[DAT510]

They don't.. Not even at stop lights, they inch up until they are in The middle of the intersection.

[ggzilla]

When we lived in the Bay Area, we called that a "Hollywood Stop". Sounds like it has now spread even to Norcal...

My whole life I have heard it as the California Stop, maybe because I dont live in California. It really makes me mad when someone does that in front of me and then proceeds to drive 5mph under; I thought the person was in a hurry to go somewhere if they cant make a complete stop...

[datzenmike]

The law is you must come to a complete stop. In real life most don't because it's a waste of time I no one is coming but where do you draw the line? Roll through at 5mph? walking speed? running? Maybe just not even bother to slow if it's clear. I stop completely much of the time and come very close to a complete stop the ones I miss. I'm not perfect but if you start slacking in this you begin to take other liberties with your driving through sheer laziness and years of having nothing bad happen. As far as driving I go slightly over the limit, maybe 3-5 KPH. This way I'm speeding just like the jerk behind my and if I'm not going fast enough for him he can pass me or leave earlier the next day. I'm in no hurry to get to work or get home or anywhere else I'm going. I timed my drive to work and speeding vs. just driving saves at most less than a minute and I don't use my brakes hardly at all.

Had similar issues with vacuum leaks, I'd say check for that. The other two times I had similar issues were with fuel injected cars so may not help much, had air leaking into the intake past the MAF causing similar symptoms. I'd say check the carb(s) for obstructions or anything else that might throw off the air/fuel mix or impede/slow operation.

[ggzilla]

All you gotta do, carb or EFI, is do the usual procedue to check for vaccum leaks. Don't listen for it, because only a slight leak causes the "runs good, but dies when stopping". Follow the procedure and you'll find it.
