well as it turns out the thing is running lean and not rich. Fuel pressure test shows that with the key on engine off 20 psi (supposed to be 35-45 psi) and key on engine running shows 30 (supposed to be 30-45 psi) my auto teacher thinks that the lean condition could be caused by an exhaust leak thats letting air get to the O2 sensor. This doesnt make sense to me because i would figure the computer would richin the mixture, right? I put the car on a 5 gas emission tester and it showed an O2 reading of like 9.04 and Co2 reading of 8.01. There are no codes in the computer on either KOEO or KOER. any suggestions?
