i do not recall the original codes but they indicated a bad IACV which is why I replaced it, and cleaned the throttle body before replacing the computer. Dealer tested IACV said it was ok and told me to replace the computer. No codes after replacing the computer. What do you mean by clean the throttle body? Maybe there is a more involved cleaning process compared to what I did.
There were 7 codes, 3 indicated a bad IACV and it fell apart when removed- new IACV was checked by dealer.
