Angry High idle, tach, temp, and gas not working AND to top it off, I cannot scan the car.
Just resently my car started stalling and wouldn't always crank.
Now it cranks every time (so far) but it idels high and the tachometer, temp, and gas gauges do not work.
Car is an 01 trans am a4, bolt ons, Frost tune

Where should I start?
Cam sensor
IAT
TPS
o2
MAF
How can I go about testing the parts?





And why in the he!! can I not scan the d@m thing!

All fuses are good. Could the security (vats) have any thing to do with it not scanning?

Post in the PCM/Tuning section. They will know how to help. Good-luck, I know how frustrating PCM/sensor issues can be.
