Tackling this misfire. I'm not a noob lol.. Please give me some input
Yes I Posted on n54tech... lolll
The other day driving with some e85 in the tank map7 and my methanol kit barely spraying I did a WOT throttle pull. Well a couple of them lol. I am in 3rd and get a misfire and the car sounds like a truck. It was happening at the track recently also. But I restart the car and it usually goes away. This time it did NOT go away upon restarting the car... I was getting misfires on 2 and 5.. sometimes 6.. The car was running really really bad. I looked at the plugs and checked the gaps which are gapped at .022 (the one step colder NGK's) picture attached. I replaced all new coils today and now I'm getting a cylinder 6 misfire only. and the car isn't running as bad. I'm guessing because only one cylinder is misfiring now. I moved the coil packs around and the misfire did not follow... What else could be my problem thats causing this misfire? I also washed the engine bay but the car started and ran fine after that for a good 40 minutes. and I used a leaf blower to blow all the water out. The plugs were dry. Not wet. Could it still be an injector? The only code I am getting is 29D2 Misfirings Cylinder 6.

since all coils are new, swap the plugs. if not then its injectors.

Can I switch the injectors around? Put cylinder 1 in cylinder 6? To confirm it is the injector?

I myself never tried this method as i have also read that the little rubber on injectors goes bad upon removal... Conflicting info huh... When i had cyl 5 issues i just changed that whole injector for a new one after trying all the other less expensive options |

I just had a walnut blast done a couple 1000 miles ago. I took the intake manifold off and they are still clean.
It's a constant misfire. It doesn't go away. Ughbbb

Sounds injector related.

So since I have the old index number I have to upgrade all the injectors ? (
Is this covered under any type of recall?
