manifolds mostly only turn red if the exhaust is clogged. check the cat.

Check and remove cat, also check how lean or rich you are running. Perhaps your tune or chip was programmed wrong.

no cat and the air fuel mixture is good at idle ed wright checked when i was up there

Evil Eric

thats the only thing i can think of to, check the tune. do you know what the AFR is?

billy mensch

wonder if the opti crapped out and can the o2s cause it to buck down low and the manifolds to get red it ran real strong until it started sputtering just the manifolds were turning red
