[quote:7508d66884="jeffb33"]i have a 96 lumina with a 3.1 when the engine is completly cold it runs fine, when it reaches oper. temp it will lope until it stalls and it misses when driving until i get on the throttle a little, ive replaced the tps,mas,cleaned the iac,replaced the plugs,wires,thermostat to no avail, when it stalls after loping it throws so many codes i wouldnt even know where to start,i cheched fuel pres, it was fine, this car is driving me crazy! any help would be greatly appreciated, thanks jeff :([/quote:7508d66884]

Each code means something
It will be a great if you can post them
Let’s do this first
Check for a vacuum leak s check if you have good flow out of the exhaust pipe
Check or clean EGR valve and if all ok and good
Then clear all codes and drive car until check engine come on or stalls
Read codes and post them
Good luck
