Intake air temp causing car to run lean MSPNP1
I think I have tracked down an issue where the car runs very lean once it heats up and the hood is closed. The AFR jumps from around a healthy ~14 to closer to 16 and fights to idle smoothly. This is setup with the maf delete so the GM ait sensor seems to be playing havoc or the calibration is way off!
The sensor is near the filter on the hot side of the engine but I wrapped the intake in insulation.
Should I swap the sensor out?
