I have a 93 4 cyl Camry with a problem that none of the mechanics so far, including the dealer, could fix. After driving for a while the idle speed starts dropping until one stop light the engine stalls. It looks like it will run for ever at highway speed. Also seems to be heat related since it only happens in the summer. Here are the things that have already been checked, repaired or replaced:
EGR valve Thermostat Temperature sensor Distributer assembly MAP sensor ECU
I am getting very close to giving it to the Salvation Army. Does anyone have any other ideas? Have you seen this problem before? Thanks.
