Passenger bank no firing Ok ya'll, I have a bit of an issue. Right now the car fired up and ran fine cool. Once out on the road and cruisin it started misfiring. This happened before, and we were pretty sure it was a loose connection from harness to coils. You could wiggle the connector and the passenger bank would fire and then miss. now this has absolutely no affect. The battery was shot, so we just replaced that as well and no change. anyone have any ideas?

ok, so i just went out and played with the pass side coil pack connector(big white one) since that has seemed to be the issue the whole time. looked like the ground female connection is a little loose. So i bent the male end up just a touch. fired it up and seemed to run much better. actually was idling right and you can def. tell when it's hittin on all 8! it's still droppin that whole bank intermittently when i rev it and try to drive it. I'm guessin possibly replace that whole connector? this is drivin me nuts

well, swapped out 02's, ran great. then found a pcv leak, fixed that and it ran perfect. then back to droppin a bank and sputtering. 99% sure it's now a PCM issue. Either a voltage spike from the alt. or a bad pcm. I had gotten a mail tune from TSP who said that the pcm was fine at the time. so we are gonna swap out the alt. first.
also, the rear o2's aren't maintaining a number. they are set at 447 but will jump up and down randomly every once in a while...
