Have a friend that I was diagnosing an intermittent idle spike from about 900 to 1400.
It's throwing a DTC 0122 & 1122, do y'all think the sensor is just toasted?

They are all TPS codes - low voltage or intermittent low voltage. Perhaps the idle needs to be tuned. The high spark peak is due to a choppy idle and is caused by the Idle Underspeed/Overspeed spark tables. It will peak/trough at +/-9* depending how far out the Idle RPM is from the deisred Idle RPM.
