Help! fuel issues and O2/knock codes... i've been having a problem lately with my car throwing codes intermittently. the codes are always O2 sensor 1's and knock sensor #2 low voltage. i can clear the codes and they may not re-appear for a week or two. anyway, on the Predator, i do not show any knock retard (it's always 0*). however, on the LTFT's, the computer is adding fuel to the max (25%)?!?! i thought at first it was an exhaust leak, but i can't seem to find anywhere where it's leaking (checked air tube block off's, header bolts, collector & flanges, etc). my car has SVO 30# injectors, ported heads, FMS cam, and was tuned by Thunder Racing on the dyno. any help as to where i should start? i was wondering if the O2's were bad, but why is it also throwing a knock sensor code at the same time?
