I was wrong on all the misfire codes, they popped because we pulled the coils while it was running to find the miss.

I can't figure out how to data log with this sct xcal3 so I don't know whats going on with it.

aaahhhhh gotcha, just wondering also, im not at work right now so i can't look it up on my shop key. how are the ignition coils wired? maybe you have a misplaced ground for bank 1 ignitions coils? i think that all the wires trace back to the pcm for the coils but like i said im not at the shop. this would explain why you have weak spark on one bank AND why the problem doesn't switch banks when you switch coils.

I tested the wires and compared the volts on both sides and the match up. Trust me I have tested everything and just keep scratching my head. I think its a fuel problem or a pcm problem but need to datalog to find out.

I almost had a priest come over and throw some holy water on the car and exercise the demons

LOL funny you said that. The other day I had a wire loom melt from around my line lock wire and drip on the headers. I saw smoke then my buddy yelled FIRE!!!!!!!. I poured my bottle of water on it and got lucky that there was no damage.

Yeah it would be bad to lose the $20K I have in this car plus the cost of the car, but at least my headach would be gone

I know you said there was gas on them when you pulled them out, but how much? Seems to me like that side is not getting enough fuel, if it were the comp, then in all likely hood it would not run or be all fugged up.

Yes there was gas on them and when pulled you can see that they were wet. I think that they are not getting enough fuel because I do get lean backfires and I can see it go lean on my wideband. It is either in the tune, computer failing, or bad o2s. But I am not just gonna waste money and throw parts at it without knowing for sure. So I guess I will wait till sat and have the tuner twll me whats wrong and what needs to be replaced.
