Ok, everything was spot on,got a little leaking at stock head gasket. We replaced them, now 02s are screwy bank 1...idles mid 400s...bank 2...mid 900s. Bank 2 will switch l r bank 1 doesn't. Swapped sides same thing..new 02s same thing. Checked grounds all look good can't find any vacume leaks. Any sugestions?

Thanks

 

Im not sure what that is but I do have another question for you. What head gaskets are you running??? Please dont tell me that you have stock ones in there

 

If they are mls gaskets they will be fine. If not, oops.

 

It had stock ones but they gave up on the dyno..I wasn't suprised. MLS in there now. Scott (Gomer ) tunes my truck ,came by my shop and fixed the problem. When I moved the 02 wires on the passenger side I just moved them forward. Well..I should have cut off the one for the rear 02 then I wouldn't have pluged the 02 into the wrong plug. It's fine now to Gomer..

 

GOod deal you found it. I was going to suggest an exhaust leak, but it didn't really sound that way.

 

LOL.. you know who takes care of you I'm just glad it was something simple. Give it HELL tomorrow at the track
