try the spark plug non fouler trick for the O2 sensors after where the cat(s) were. Do not do this to the main two O2 sensors that were on the manifolds. Only the O2 sensors that were after the cat(s).... Here: http://www.ramforumz.com/showthread....ghlight=fouler

Scroll to the end there is pics by cheffred...

Right so do the non fouler spacer trick on the rear two sensors. Or are you saying you already tried this? The code is probably P***** "bank 1 sensor 2" and "bank 2 sensor 2"

hutch, I understand you got your issue resolved, can you post exactly what you did, so I can update another thread I have that pertains to this issue. Mainly I am looking for info on the steel wool part of it... thanks

Hold on, the way I read that he had the fake cat sensors before AND after the resonator, as in, had fake cats in place of the O2s you actually NEED to be in the hear and in the ehxuast stream...

Right??

________
I think he has long tube headers with upstream O2 sensors, then resonators(fake cats?), then downstream O2 sensors...

The non fouler trick in the downstream sensors should have done the trick for him. I think it didn't work, then he added steel wool in the non fouler and it worked.
