The only code I have left is in the koer part. Its a code 44r which is a thermactor issue. Thing is everything works and the cross over tube is clear. Heads were cleand and worked on when the motor was rebuilt. I seem to remember the crossover (air injection thbe) being cleaned as well.
Could a bad one way valve cause this code? I can swear I can feel something coming from that air injection tube when i take the hose off.
