1991 OCC. Was surging at idle and getting intermittent check engine light on startup. Light would usually go off after several minutes of driving.

OBD I blinked a code 22. Ordered NHK TPS from Rock Auto ($18). Installed easily with 2 Torx screws. Problem solved.

I understand that later models have a bracket that needs to be removed to access the TPS screws. Still an easy DYI.

I had an idle issue that would not idle fast enough, or too fast. I swapped out the AIC, and that has calmed it down. I may swap the TPS too, just for funzies.
