Ok, here we go. I was driving around awhile when the car started to run like a freight train. It was surging or chugging under a light load. When I floored it, it ran smooth again. I drove home and let it cool down and then went out about 2 hours later an took another drive. It ran perfect all the way through the throttle range. I got about 2-3 miles down the road and the same crap. Chug, chug, chug. Floored it, and it ran good. I noticed my Air Fuel guage was reading lean at WOT. I had a mechanic buddy check it out and he suggested the O2 was bad. I replaced it with an old one I replaced that one with. Same deal. It is obviously a sensor of some sort due to the fact that it only acts up when it finally reaches operating temp. Possibly the computer is going south??? Beats me. I am going to replace the MAF tomarrow with one I have laying around from another intake I had. I can hook it up to a laptop but I am not sure what values I am looking for on the sensors?


HELP!!!

 

I found the problem. It was the MAF sensor. Runs great now.

Thanks anyway I guess??
