Re: 700 MILE 1989 TRANS AM TURBO

The miles are from the trips to and from the tire dealer and the smog check place. The bolsters however, show 30 years of sitting in it and revving it.

Re: 10K resistor - change the driving characteristics of the car

I don't think it's field service mode because the light doesn't flash while the engine is running and I'm data logging. It should flash to indicate rich/lean in field service mode, right?
