And we are DONE! Purrs like a REALLY big kitten! No more SES light, still have ABS but thats sensors...Replaced all 10 plugs with autolite plats, didnt need to replace any coils, all their resistances checked sat against the numbers in the Haynes manual. Several of the plugs I pulled were way over gapped, and some of the coils seemed like the springs were stuck up in there and not making contact...
Anyway...10 plugs, a few new toys..er..tools.., PCV, EGR and DPFE...6 codes cleared.
I've decided I am going to let the dealership do the Headers...need the warranty.
Still shuddered a little bit, but I convinced myself it not a misfire, must be something loose...like the Exhaust manifold!! $630 later, manifold is on great, new gaskets, studs and bolts...and we're still shuddering..
I'm gonna have to say its a misfire..again..but no codes.
Can I get a list of possible suspects in order of probability..
These are the codes I pulled before I DC'd the battery..
