If I were to turn my car on with the a/c on, it will idle funny and die. So I HAVE to turn it off to start the car.. but when I turn it on after that, when coming to a stop, it dies. The idle goes up and down and it dies. Only after driving for about 10-15min. can I turn on the a/c and it be okay 90% of the time. What is causing this? I attached my tune.

Goto System>A/C and increase the torque loss table until it runs right.

I had to bump mine up close to 80%.

The only thing diff. I see from your tune is the A/C Enable TPS and the A/cEnable time. The A/C Turn on and off Delay are the same as mine.

Have a look at how many steps your iac motor is at idle with the scan tool. If it is maxxed out no adjusting of the idle airflow correction tables will help. Also there is calculated pids in the scantool for airflow correction aircon on. Log these with the corresponding pids & it should help you find the problem. Also have a look at A/C spark correction.
