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.
