A rich air/fuel mixture has been indicated by an abnormally lean correction factor. Bank 1
That was the breakdown of the DTC.
It has a very rough idle at stops and thats when the MIL Illuminates.
The MAP sensor is one of the sensors that control the Pulse width of the injectors.
I believe the O2 sensors on bank 1 also control this function.
Anybody know of any other problem that would create this condition?
Or any thing I should check?
Thank You

Stuck injector, or possibly fuel pressure regulator.
If you can read the long term fuel trim, numbers that are -12 or higher, would indicate a contminated MAF.
