I NEED YOUR HELP! I have a 1996 Lumina sedan with a 3.1L engine. Starts fantastic all the time. when the engine is cold, the second I touch the gas pedal it sputters, runs rough, and stalls. I can restart it with no problem, idles perfect. Again, the second I touch the gas, same problem. If I let it idle for 10 minutes until the engine reaches about 140 degrees, no problems at all. Runs like new. I have changed the Plugs, Wires, Fuel pressure regulator, Fuel filter, Replaced the fuel injectors, Temperature sensor for the computer, and the Throttle position sensor. Please help, I'm at wits end trying to solve the mystery since it is a COLD ONLY problem. Frustrated_1
