Thanks everyone for the help. Tailgator, your correct, mine uses the MAF. But it turned out not to be to common knowledge as to this particular year not having one. I had even bought a Haynes manual, they even showed a picture of where it was located on the fire wall. But once you started looking at thier diagrams, the one for my VIN# did not show a MAP sensor. So now I have to diag other things. Having problems after about 60 miles of driving the Check Engine light comes on, and power disappears. The light cycles on and off. But the power fluctuations are not in sync with the light going off an on. If i'm idling and the power comes back, drops the tranny into first gear and takes off, fraid of dropping the trans like that. On the highway, I will loose anywhere from 5 to 10 miles an hour until it cycles backs on again. any ideas?
