Hi people
I replaced the plugs and the pvc valve, reset the computer . I drove the car for a week then the check engine light came back on. Except now, I only have two codes, EGR valve and Knock sensor. I just ordered a knock sensor for $122 it's a standard. I read that these cars just go thought theses sensors and if I replace it, I will eventually notice an increase in performance once the computer learns to advance the timing. Well, no one gave me any type of help so I will keep posting just in case someone else is in the same situation. The plugs were NGK platinums. like 2.98 a piece. The two O2 sensor codes are gone. Two down ,two to go. I plan on installing the new knock sensor and cleaning the EGR Valve. I'll keep everyone up to speed.
