When put the car in gear or turn the air conditioner on the idle goes up and down until the car quits. When I put the transmission in natural it goes up and down, but stays running as long as air conditioner is off. I replaced the throttle body twice and the o2 sensor.

Scan for codes and check for a vacuum leak, clean throttle plate on both sides and iac hole with choke cleaner. Also check for air leaks between air cleaner and throttle body

Here is a link to an article that features written instructions and pictures explaining how to do the scan yourself, also I have included a link to our YouTube channel with a how to video on code scanning. Most scanners are inexpensive to purchase, you can purchase one from Amazon.com. Once you have the codes please get back to us so that we can further assist you. Thank you for visiting 2CarPros.
