20v 4age dies when A/C is on - 6G Celicas Forums

Anyone know what the problem may be. When I turn on my car and turn the a/c on when the engine is cold the idle is fine at 900 rpm. But when the engine is warmed up while driving on the road and then I need to stop at the light, the idle drops and fluctuates from 200-500 rpm and dies. I know it can't be the Idle up valve because I already tried taking a look and cleaning it out with no changes. Any suggestions would be great smile.gif

Has it done this since you did the swap, or did it start recently? Did you ever hook up a VSV like I showed you?
