Thank you for this info. I called your shop last week and we talked about flashing my PCM and I think I need to save up and do this for the car to run right. You had suggested switching to OBD 2 instead of flashing the OBD 1 PCM. My problem is that I've bought all new sensors and spent a lot of time on the wiring and I'd like to not redo all that. This engine will remain stock other than the removed emissions stuff.
