I have done my research and to no avail. My car runs sweet when it is cold i get that pushed back into your seat feeling when it just starts and all the way till it reaches full operating temp. Then...... bam it feels like there is no turbo on the car at all. i have checked all my sensors using MMCD and all is fine except the mas. ( ran like this before the mas codes, i have a new one on the way also) i was wondering what would cause this SMIC, coolant temp sensor, timing, I don't know where to start. I have installed an a/f Gage and i am running rich according to that and MMCD says that my trims are all 118.7. its like the first 15 min of driving the car its perfect then it starts to stall when i stop and just runs horrible.
