1993 grand prix dying

I have a 1993 pontiac grand prix le 3.1 and it keeps dying on me. Right now it is mainly when i come to a stop at a light or stop sign. When it dies I can turn it over and push the gas all the way down and it will start. But then for the next couple of stops i have to work the gas and brake to keep it from dying. I have changed the low coolant sensor, fuel filter, crankshaft sensor, ignition module, coils, plugs and wires. Now everyone is completly stumped as to which way to go. I need help please.

Your engine needs to re-learn its idle parameters. disconnect your battery for a minute or two, then reconnect and start vehicle and apply park brake and put it in drive. let it run for 10mins then shut it down and wait another minute and start it again and let run 5 mins. that should do it.

Provided you don't have a vacuum leak, (check all hoses for tightness and cracks with engine running) it's probably your idle air control valve or sensor.

My 1999 grand prix stalls and dies at stops.


My Pontiac Grand Prix is also a 99, it has 216,+ thousand miles on it, it runs great, idles good, I need to replace the oxygen sensor tho as it shuts off on me while driving or sometimes coming to a stop. You might try checking the fuel filter and pump as well.

My 1993 pontiac grand prix with the 3.1 engine stalls when it idles at a stop light but it starts right back up. it has plenty of power. we changed the o2 sensor did the vaccum leaks and ths spark plugs....


The next thing to try in regards to the stalling would be to change out the Throttle Position Sensor this sensor is the usual cause of this symptom.

Car drives good but it died while driving


I'm leaning toward a bad crankshaft sensor. There's a couple of experienced GM guys on here, so we'll pass it by them first just to be sure.

Idle problem


throttle position sensor is what I replaced on mine. Could also be a short in a wire that controls throttle. That was 6 years ago and it was $100. Took it to a shop, that's all I got.
