Okay, lets fix my spuddering issues

high end misfire, completely random. When revving it when stopped and while my friend was driving behind me it smelled of unburnt gas. Judging by this, it is a spark issue. It isn't consistant, sometimes it boosts perfectly and I half shit myself, the other half of the time it falls on its face.


Coincidently, my N/A spudders too under WOT sometimes.



My bet is on ECU, any input?

Plug gap? Wires? Coil pack? Battery/alternator?

My bet is coil packs or PTU. My R/T TT does this, but it pops and misses at idle too, so I'm guessing PTU or coil packs, because I know my plugs are gapped right and my wires are relatively new.

It could be the ECU itself, though..
