My wife’s 1998 Nissan Altima , 100 K miles, starts to shake and stall in the summer when the A/C is on and she stops for a light. Anyone have any thoughts ?

Cleaning the throttle and Idle Air Control circuit might be all that is needed.

I agree with **Rod Knox** especially if the engine runs OK without the AC on.
