I'll also update on my CEL situation. I found a computer for a 2000 V6 OHV w/ manual trans, so that I don't end up with the Trans control throwing codes. However I forgot about the PATS system, so while I don't get codes thrown in KOEO, I can't start it either. I'll have to get someone that has a PATS programmer set my keys as the master keys in the PCM, or get another computer from a 97 and see if it will work with the 2000 harness. EDIT: And fuel mileage: My highway mileage has gone up about 1mpg, but my city mileage has gone down ~4mpg.
