Im about to pull my damn hair out Man we have been fighting a stumbling problem right when the car is coming on hard at about 5500 and I dont know what the hell is going on. The car is popping and stumbling once you get it in the upper rpms any ideas. Programming with bs3 I can post up logs to anyone that has a idea

not enough timing, wrong plug, wrong plug gap, weak coil(s), plug wires, too much octane, too much fuel
interesting this popped up because out of nowhere my car did this last night.
i was hoping in my case it was a fouled wideband.. but that doesnt seem to be the case....i have filled it back up with 93 (had 5 gal of 1100) and it seems to be clearing up.. weird.

what is the hosepower you are putting out because it could be any of these problems and all of the those parts that mightymouse had named they all peak out at a highhorse power range or over peak with the fuel

Im going back to mess with it today and play with it. I just got the car running and Ive got a baseline tune we havent had it on the rollers yet. Im running c16. Its got us stumped. Ill try disabling the cam sync and see what is going on. My plan is to take it to Mike Morillo and have him do his magic on the car but I wanted to make sure the care is sound before I make that haul.

My car did this as well for about a week before it seized up. I tried both TR6s gapped at .035 then .030, and then I switched to a TR7 and it sputtered both at .030 and .025 still.
104 octane BTW.

I had TR 6's and they were gapped at .036 I pulled them out and my mechanic and I put 10's and they are gapped at .28. We actually also had 2 msd coils that werent acting right.
