Record the codes.....Clear the codes ...Might clear up some drivability problems....recheck next time MIL comes on.
MAS do have high failure rate...O2 not so often...drive the vehicle for about 20 miles at all speeds and throttle openings to allow it to re adapt...might take more then a few drive cycles....wire looms are common problems..( pattern failures.)...throttle adaption needs reset....then recheck codes.
We await the results.
