A while back I purchased a MTM chip and loved the new found power. The car drove fine for five or six days, and one day on my way home I floored it to pass someone and the car stuttered like crazy. The next stop light took off WOT and nothing. Over the next few days this problem became more and more noticable. Took the car in when the CEL came on and it was reading misfire on cylinder 2. I replaced all the plugs, coil packs, icm, cleaned the MAF, looked for leaks, everything I know and have read to do I have done. Normally the misfires occur when at full throttle from low rpms to right when it should hit boost the car totally craps out. Now when the car is misfiring the seat belt light flashes. Any help is greatly appreciated!

I would say your plugs are gaped to big the seat belt lite could be a bad connection but not related to the misfire.

The new plugs that I put in are the Bosch Platinum 2 which are pregapped. Should I get another set of new plugs that I can GAP myself? Thanks for the ideas. Wish it was as easy as wearing my seatbelt.

Hey figured out that my newly replaced plugs were no good and replaced them with new NGK lazer platinums. Gapped them to .028 and running great! Thanks
