I installed my Reinhart chip and a 02 GT MAF last night and I have to say I am very impressed. However, I've run into a few wierd problems. I made sure the contacts were clean, checked the wiring of the MAF harness mulitple times, and pulled fuse 15 to reset everything. Most of the time the car starts right up with no hesitation. Sometimes though, when it starts, it will cough a little at idle right after starting, and then go back to normal. A few times, it starts, coughs then dies, and when I try to restart it, it just cranks, but doesn't turn over. However if I unplug the MAF, it does start, and stays running, when I plug it back in. The only things I can think of are that the intake is choked, or that I haven't given the EEC enough time to relearn all the current settings. Any ideas?? Thanks!
