LH codes WON'T send the car into ASR limp mode. ONLY codes from the EA will affect the ASR system UNLESS the ABS lamp also comes on!

Scan the EA/CC/ISC system for codes, could be something as simple as overcharging.

IF you are getting MAS codes for the left side then check the MAS on the "right" side as well as the air intake rubber boots that attach to the intake on the RIGHT side.. The intake does cross, so the MAS on the right side is for the left side of the engine.
