I was in a bad mood earlier because I had to pay my mechanic $285 for the 3 times I took my car to him to figure out this problem, which is still a mystery. He said the car is possible going lean at highe rpm's. I don't know how this can be only when the car is warmed up. He tested the fuel pressure and did a battery to computer aid tests. My plugs are slightly black meaning it's running rich more than lean. Can a car run rich at low rpm's and run lean at high rpm's? I have a new mass air meter that I had on the car for a week back about 4 months ago and it made the car run very rich,popping exhaust,surging at idle. It says on it was calibrated correctly for my injectors. The car ran great for a week after that when I put my stock mass air back on. Could the mass air still be the culprit?
