At some point you will need to verify fuel pressure and consider possible failing fuel pump.Early on these can be intermittant causing fuel loss to the injector.key on/engine off cycle will run the pump for 3 seconds.In a quiet place,like an enclosed garage you can listen to the pump running and many times in a failing state,it might sound abnormal,louder and squeelish in a sense which may substantiate this possibility.Other possibilities include air flow meter connected to the air intake tube.These were notorious for cold solder joints inside the electronic board.A tap test is helpfull on this problem.Gently tap the air flow meter and if it creates a miss while doing so,this could certainly be the culprit....good luck

Engine Rotates (acts as it will start) won't fully turn over.


Did you replace the TPS (throttle position sensor)?? Try that if you haven't so. But if you did that already, and still getting the same problem, I would suspect the fuel pump going bad.

1991 Buick Park Avenue sputters at random, stalls-egr problem?


I would look at the Map Sensor or the O2 Sensor then the EGR Valve. As far as I know all vehicles have EGR valves. Get the Haynes Manual on your vehicle for location and replacement steps for all of these. It could also be a Throttle Position sensor or clogged or malfunctioning injector units, the Haynes manual will assist you in isolating these.

Stalling


I am dealing with the same issue. I have had the computer checks and there is nothing to indicate an issue.There were no computer error codes yet I stall at red lights.

The O2 sensor, the speed sensor or the MAP sensor may be one of the problems. The MAP sensor measure the air pressure in the manifold. It is commonly mounted on the fender and is low in cost and easy to replace. To test it if your if your car won't start, unplug the electrical connection from the MAP sensor. If it starts, then you know to replace the MAP sensor. The Hall Effect sensor can fail and not set an error code. This is an inespensive part that sits underneath the rotor in the distributor cap on cars without distributorless ignition. This only applies to cars made after 1996. Also check the fuel injectors and fuel filter.

If you have a burglar alarm, make sure that it is not causing the problem. It often times can cause the stalling issue.

Throttle/Idle/running problem - wants to run too fast, or stall out


RPM's up and down check EGR valve and sensor. EGR valve and sensor control idle. That's why your getting the surging on rpm's and this could be giving out the other codes. If mass flow was bad car will not start and the same for the map sensor. O2 sensor measures gas and air for right mixer. TPS controls 0-60 speed as in throttle respons.

1992 chevy corsica runs rough,stall or dies after stopping


Sounds the EGR valve and EVP sen is bad even if you tested it. The EGR valve cntrols idle and if carbon up will make the car stall or idle high and low (rpms going up and down) This was common on all cars during that time. I would say replace the EGR valve and senosr. This should take care of the problem. One more thing have the fuel pressure check on the car.

. Have it checked for a trouble code. It seems like a sensor problem. ( Idle position , crankshaft position, camshaft position sensors could be bad. Also the EGR valve could be bad. with a caode you can narrow it down a bit.
