Question about 2002 Chevrolet Impala

Open Question

1999 Regal stalls without warning

1999 Regal will stall at any time without warning. Regardless of whether the engine is hot or cold, accelerating or braking. Car normally starts/runs fine immediately after it but now I had an instance where the engine did not turn over until about the the fifth try of starting up again. No engine codes show up it stalls. Lights/radio stay on when car stalls.

Something that may be related is at times the traction control acts up putting on numerous warning lights on the dash (check engine soon, anti-lock brakes, trac off, etc) but it's not clear if this intermittent problem is related to the car stalling randomly. Exact same problem with my Impala, usually stalls while decelerating or cruising about 35 mph. Checked NUMEROUS items, no luck!

    Make sure first all vacuum lines are in good condition .. Then my guess your EGR valve is leaking by at times causing it to stall when you let off the gas or stop at a light or sign thanks jerry let me know scott

It could be one of a number of things...Ex: Fuel Modulator, Vapor Lock...What does it do when you try to crank it back up?

try looking for a button that says trac or traction control. She may have addidently bumped it. If its an automatic it may be by the shifter. or dash or steering column.

SOURCE: 2003 Chevy Impala Service Traction Sytem show on Dash

I can't answer the question about the gas fumes, but I had the same problem last year with the "Service Traction Sysytem" message and the Trac and ABS lights coming on in my Impala. Mine turned out to be because of a bad wheel bearing, that was causing the ABS and traction system not to work. I'm not sure if you've experienced this, but another thing that would happen with mine was that I would go to brake and have a hard time depressing the brake pedal, almost like it was pushing back. That is the point when the Trac and ABS lights came on.

SOURCE: 2000 Chev Cavalier, warning lights are coming on

Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with some of the components it stores the correspondent trouble code(s) in its memory and lights up the Check Engine, Service Engine Soon, ABS Or TC lights to tell you that there is a problem and you should have the car diagnosed and repaired. The number of codes that can turn the light on number in the hundreds. I would take it to a service center you trust and let then come up with a solution. Sometimes a problem in one system will turn light on for other systems that communicate with it, but it doesn't mean there is a problem in all of the systems.

Have a 1995 Buick Regal. Car stalls when braking at a stop sign or braking into a left or right turn.RPMs drop to 500 then stalls without warning.Car starts right up with no problem and runs great.


Do you hear a sucking noise from under the hood when you apply the brakes? You could have a bad brake booster venting too much engine vacuum when applying the brakes causing the engine to die.

2000 Lincoln Ls Stalling While in Motion


Check the water temp sensor. I'm not too familiar with Lincoln, but on GM vehicles a bad water temp sensor will tell the computer that the engine is cold causing it to dump more fuel than it really needs thus flooding the engine. The only way to start the engine is to open the throttle body enough to get the air/fuel ratio right so it will burn. If that doesn't work look at your EGR system to make sure the valve isn't sticking. It should move freely. If it's binding then it can cause similar issues, though not as likely.

2002 jeep Cherokee 2.5crd engine cuts after removing foot from accelerator pedal . no warning lights come on. let the vehicle stand for 10 minutes then it starts up again. can it be injectors or ignition...


check all fuses.
cuts out hot or cold engine.????????
if it wont start and car gets 60k tuneup (?)
then connect scan tool and crank for 5 seconds.
see if you get scan DTC errors , cranking (release key) see em?
stalls are caused by over 50 reasons. guessing is impossible or very expensive.
enter: Diagnosis,
you take measurements, and find the failure path then work that path like bird dog.
2.5L 4cyl engine. I just sold min last week. with 5sp M/T
cuts out, does that mean the engine stalls?
we need to know what it really does.
1: stalls (engine rpm drops to 0 RPM)
2: engine rpm drops to 300rpm and shakes.
3: power loss from engine?
4: only stalls at stop signs...?
5: bogs all them time, same as #3
6: engine misfires (shake)
7: bogs only on throttle TIP-IN then recovers.
8: bogs only on hills.

i wait.
when dead, is spark lost?

Stalling engine


look in to the throttle body right before the throttle plate and spray carb cleaner in the throttle body .
clean all the black carbon out .this carbon builds up around the throttle plate and causes the idle to drop cause it cant breath.use super unleaded to prevent this from building up again.
hope this helps.

thank you

1993 buick regal start and stall


The average life of a battery is 3 good years, regardless how BIG, or how it cost. Anything after that is a blessing. Personally, I would replace the battery ASAP, and then with a FULLY CHARGED battery. Then drive, and see if the problem still remains. Hope this helps

199 Jeep cherokee stalls without warning


Does it start right back up after it stalls? make sure all conections are tight at fuel pump, sounds like it could be loosing ground at pump, or hot lead is loosing its connection at pump.Also fuel pump relay could be getting hot and quits working.
