OK, Heres the deal. After numerous attempts to find out why my check engine light was coming on, my mechanic determined it was finally my Don Moody intake (Hotshots intake). It seems the light hasn't come back on after the switch back to the stock. Is this possible? I've had it on for over a year and a half, and really enjoy the chrome look. Any ideas on why this may have been the cause? By the way he said it was a problem with the intake air control sensor.
