Engine Stalls at Stops with A/C On

Toyota stalls on hot days with air condition on …it stalls at stops only when ac is on…new tuneup…..replaced idle control valve……still stalls



Hi there ,

I would clean the throttle body bore first, check the base idle speeds second, third, check for a possible vacuum leak under the hood.

Here is a picture of the throttle body
