Very rough idle then dies
I have an 05 mustang gt I installed AFE CAI a few days back and the car ran fine. Went to crank it yesterday it would barely idle and cut off idle was so rough it sounded like it had a cam. It did it this maybe 4 times before it would idle properly. I'm fairly new to the mustangs could this be a dirty MAF sensor?

Check that all connections are tight to make sure there are no air leaks.
Since it was running ok prior to the CAI I wouldn't think it'd be a dirty throttle body but doesn't hurt to check, it could need cleaning.

Therefore I'd highly recommend cleaning it.

Quite a few No-tune-required CAI's run on the ragged edge of needing a tune but the additional airflow can simply cause issues if the TB was dirty even though it wasn't running poorly prior to the additional airflow. TB cleaning first, then see what's happening.

Here is a small write up I did a while back on the subject.
