I purchased a 2007 Mustang GT 4.6 a few months ago. Very low milage (10k) and several performance mods already in place. My local Ford Dealer (who deals with alot of performance modified Mustangs) checked it out and confirmed the following mods: JLT Intake, Long Tube Headers, Borla Catback Exhaust, IMRC Deletes (Throttle Plates Deletes) and 4:10 rear. The car is excellent. However,
The guy we purchased the car from did not have the programmer for the computer. I purchased a SCT programmer and 3 custom tunes. The car now runs better than ever. I needed to run the car thru NJ Inspection, so I acquired a custom tune just for that purpose.. Basically just to get the OBDII readiness to complete. We drove the car for a few days, tried to follow the Ford OBDII Drive Cycle, but several Monitors are still not complete. O2 Sensor, O2 Heater and Catalyst monitors all still say incomplete on my scanner. We had SCT check the tune directly and they say all should be good. I re-loaded the tune and tried again. Still get the same results. The EVAP go to OK after a bit of driving but the same 3 monitors will not complete. I drove the drive cycle this morning for about an hour and again this evening but still no change.. The Dealer confirmed that the 02 sensors are operating... Does Anyone have any ideas??
