Well I threw a CEL for system is to lean w/ the SS/SC...from Bank 1, which if I remember correctly is the O2 sensor off the exhaust manifold. I have come up with a few things, but I thought I would throw it up on the board to see what suggestions could get thrown out. I threw the CEL friday night after a deceleration for 3rd to 2nd and came out of the clutch at little too fast and too high of rmp's and the CEL was thrown. BTW I am only running an Injen Intake with 89-91 Octane gasoline as its fuel source. I have been running this intake with no CEL's for quite awhile now. Suggestions welcome.
