1992 Lexus ES300 Q&A
1992 Lexus ES300 Question: How do I fix my car if it keeps stalling everytime I come to a stop?
That year range the idle air control valve sticks or fails (it's right under the throttle housing). I have had great success cleaning the valve but it's foolish to speculate without first checking the basics. Check for vacuum leaks, clean the throttle housing, make sure plugs and ignition system are OK. - patrick mannion
