I was busy with work the past few days, but im gonna work on it first thing in the morning tomorrow. I also noticed the spark plug wire clips that tighten the cords to the coils are all missing. I guess the previous owner discarded them. Those tiny black clips are also discontinued at the dealer. So I need to get them at a junkyard. Do you think those clips make a difference? Maybe a few are not tight enough to get a connection?

I don't think those spark plug cord clips make a difference, so just ignore my last 2 posts.

btw the iridium ix plugs were not pregapped, they were .038, i regapped them to a .030. It still didn't change anything. I also made a new ground wire for the coils. That didn't make a difference either. When I pulled the plugs, 5 and 6 were completely fresh as if they never fired. I'm starting to think that one of my coil packs are bad. I'm going to get a meter to test everything.

Thanks for everyones help, but it was a faulty wire from NGK. I bought bosch ones from autozone, and car runs better than ever. I bought the NGK wires from Nopi, they will be refunding me. Thanks everyone.
