Hey guys, I've done some crazy researching about this and haven't been able to pin down a solid answer for my problem. It's a two parter, so bare with me.
I have a ton of misfire happening over the entire rpm range, boost or not. Even idle has some misfire. I've done some diagnostics and found that when I plug a timing light to the coils number 1 and number 3 fire consistently. Though, number 2 and number 4 seem to misfiring. I read that misfire on two coils means your coil pack is going. But I thought that 1 and 4 were connected and 2 and 3 were connected. Is it still possible that the 2 and 4 could be misfiring together? And that would make my coil pack bad? FYI I have brand new NGK 7es's gapped to .030.
I also noticed when I do a boost leak test the air seems to run straight through the head and right out of the exhaust. I can't find a leak anywhere, but the system only holds 3 psi. You can clearly hear it dumping into the header and running right out of the exhaust pipe/wastegate. Should this be happening? Would something like this cause misfire?
