The car has been running for about a week and Ive put on 100 easy miles on so far. Everything seems to be running ok but i threw a code this weekend and had it checked this morning. P0301 Detected misfire on #1 cyl. The engine doesnt seem to be bogging' and feels ok. I pulled the #1 (on the left in both pictures) and also the #4 just for comparaison. They are both brand new NGK's Platinum. I am running a full 3L swap with SVT cams, UIM & LIM and mystery modded. The most likely culprit i would think are the plug wires. From what I've searched is seems the guys who are throwing the missfire codes have very noticeable bogging. Would mine have missfired for a bit and then run properly again? The code has since been cleared and I drove it straight home and pulled those plugs.
