Hello,
I am new to this forum and not new to my lumina. It has been a great car for 239,000 miles and still going pretty strong.
OK, it seems after the car sits outside and after a rainy, misty, or drizzly day the car runs bad only when applying the gas pedal. It sits and idles no problem and starts without any problems. It is when I am going down the road and push the pedal more than a 1/2" it starts to miss-fire. After the car warms up the problem goes away. It seems some moisture is getting in somewhere but I can't figure it out. I had the same problem a year ago after I gunked and washed the engine.
I know it is not the fuel pump and the plugs and wires were replaced 40k ago.
Any suggestions or things I could try replacing? I was thinking a distributor but the car doesnt have one, at least when I looked at it. Thanks for the help. I tip!
