Check Engine Soon - Problems

I had posted this in another thread, but decided to start another.

for the past 3 weeks the check engine soon light would come on, car would start to idle at 1300-1600rpm or so. the transmission in auto mode would start shifting very hard. It would downshift like it were in "sport" mode. Very weird.

this happened more than once also, would get to where i was going, turn the car off.. do my errands, then sometimes it would go away. Other times, after starting the car, it stayed and acted as described above.

Took it to dealership, they said it threw a few MAF codes. They replaced the MAF.

Last night.... it happens AGAIN... SOOooo.. going back to dealership Monday.

I am wondering if this ties into the "hard starts" that happen to me sometimes.. just like some other people here....

I'll keep you all posted

the high idle is limp mode and is caused by a code (obviously), could be overboost, could be airflow/torque limits, etc.

Chris talks about SST torque limits, not the airflow/torque limit maps.

The airflow/torque limits exist, even Ryan Gates can attest to that.
