Need help! only passenger bank fires
Guys i am stumped! After a dyno session I picked up a problem where only the passenger side(1-4) cylinders fire. I have fuel on all cylinders and have checked the cops by swapping them to firing cylinders where they worked fine. What I am wondering is how the cops are wired, in other words is there a way for a harness or sensor to shut down that whole bank.
I guess I should be happy it made 525rwhp then after when adjusting the trans settings it occured. A loud pop and a miss, I popped the #8 plug. I replaced it and have the problem described above. The only diff. between before and after dynoing was methanol inj. , jlp sheetmetal plenum, and autolite ar103& ar94 plugs(tried 94's after to see if they made any difference). The tune was pig rich. Are the autolite plugs any diff. than tr6 as far as construction?
Thanks for any responses ahead of time.
