My OBD-2 reader doesnt show the fuel trims. But the car idle's very well. Although on the highway at partial throttle I can sometimes feel the engine sputtering, it almost feels like a light head wind coming and going.

Any ideas? Could it be a vacuum leak somewhere? But it doesnt make the idle chase. Maybe charlie accidently put a stage 1 flash? But again the idle is very very good. It pretty much can sit right on 14.6 for several seconds at a time.
Do you know at what rpm you and the conditions you get the code. If I had to guess it is while cruising on the hwy.

Let me know..

Thanks,

Jermaine~
