Hi, has anyone checked for stored trouble codes? There are a number of things that can cause your stalling problem, I have found bad connections at the ECM you maybe loosing the crank signal there. Also these motors are know for the distributor shafts to wear and short to ground causing you to loose spark and shut down. Hope these help lead you in the right path of diagnosing the problem.

2004 Chevy S10 4x4 stalling at idle. Drove 3 hours last night, no prob, but this morning this. RPMs 200-800, oil pressure gauge flutters, lights dim with the idle, then stalls. Starts right back up.


can be a multiple of reasons -will start with check for fuel pressure -possible fuel pump/fuel filter ---in need of a tune up ---egr valve --cat converter--battery - these components sometimes dont set off a check engine code but if you did or do have a code have it scanned most auto stores offer this service for free

Ok here we go again 2000 buick lesabre . driving down road service engine light comes shortly after car stops dead. wait a few minutes usually starts back up light might go out get home fine. everyone is...


What you need to do is have the code checked for the service engine soon light.This will help in diagnosing what could be causing the vehicle to stop dead.By this I am assuming you mean it will stall.Auto Zone and some other parts stores will check the code for you for free.But the diagnosing will still need to be done to see what is causing the light to come on and make the car stall.Sometimes you may need a scan tool and a multi meter to help find the problem.Which means you may have to go to a repair shop.Hope this has helped you.Good luck.

Runs and stalls, wait for a min and runs again whats the problem?


well i would say if the rpm gauge stay's up and the other's all go down that would be a blown motor.

1993 Ford Escort 1.9L Auto Randomly Stalls


I don't have the solution, but I have the same exact problem on my 1991 Escort 1.9L with auto with 120K miles. I replaced the IAC with no difference. In fact I unplugged it, and still had the random stalling. Also disconnected the EGR vacuum line...still stalled randomly. After it stalls it always starts right back up again. Sometimes it will act as if it's going to stall, but comes back to normal idle. Park or Drive makes no difference. Acceleration and all normal driving is fine. The next thing I was going to try is hooking up a timing light and watch to see if the timing light stops flashing as it's stalling, and/or hooking up a fuel pressure gauge somehow, to the fuel rail, to see if the pressure drops when stalling....to figure out if its ignition or fuel related.
