Well engine and performance wise every thing is back to stock. I did have a CAI installed a while ago and never ran into any problems. Put it back to a short ram and everything was good. Left the car as it was then just started getting issues out of no where. Even with 2 of my Focus Sport tunes it still runs like crap.
Curious thow. I do have the hard wired o2 cheater still installed on my 2nd o2 sensor. Would this prevent a DPFE cel to come on?
