Mike,

Does the math (mileage / gallons) agree with what the DIC reads on the avg?
I would think that if the engine is really running that much richer, some trouble codes (too rich) would be set, unless the system is running open loop. In that case, another then code should be set after a while, meaning being in open loop too long... Of course this computer stuff is kinda beyond my knowledge...

I assume it does reach normal operating temp?
