I have a 2000 Pontiac Grand Prix GTP. The car when i start it up in cold temps runs real rough then will actually die if i don't keep preesure on the accelerator. When it idles it will go from about 1 to 2000 rpm until it reaches about 150 degrees then the car idles fine drives fine no problems. It is definitely soemting that cold is affecting. I have had it to a shop but no codes, i thought it was the E. coolant Temp Sensor, but it checked out. My mechanic said the onyl place he could start at was the Ignition Control Module. anyone who can help i would greatly appreciate it!!!
