Occasional 22
Have been getting a very occasional 22 (low TPS) but never long engough to stop, open the hood, and instrument. Have had a scan tool on and voltage recorded by ECM dropped to zero momentarily but could not duplicate while wiggling wires.
Was wondering if anyone knows of a stress point in the wiring that can short things. Last time this happened (on a Fiero) I wound up running a new wire from the ECM to the TPS but that is sloppy.

May sound totally off here but could there be a dead spot in the TPS sensor?
