if I accelerate past half throttle and once it hits 3500 rpm and above it surges or cuts in and out. It seems like a fuel delivery problem. No code. New pcm, o2 sensor, catylitc con, plugs, wires, coils are good, pcv valve. New vaccum lines. Run like a s.O.B lots of power. No prblem what so ever. Just the cutting out. Good mpg. It has 146,000. No codes at all. It has a lite blue smoke under hard accl. This problem has only occured when warm. And gets worse once up to running temp. I'm getting mad trying to figure it out. PLEASE HELP!
If you know the problem e-mail me with a good idea.
have the same problem?
