The only strange thing is that it was idling high, eating up gas, and cel was on before the spark plug change. Prior to that I had never touched the TBs.

I guess we'll see the verdict when I pick her up today.

I have a good idea youll find it to be the AFR sensors on the headers.

I had the same thing. I was averaging like 16mpgs and idling at 1100rpms and had a reoccurring CEL.
