Rough Running

I have a 1992 Toyota Camry with about 130,000 miles. It cranks fine and runs good until it gets warm. It then starts idelling bad and goes dead. I have had it in the shop several times but they cannot find the problem. This last time they replaced a fuel/air sensor that the o-ring was warn out on. But it is still doing the same thing.
Any help is welcomed.

Clean or replace the idle air control valve, or was that the sensor they changed? If so you may have a sticking EGR valve or vacuum leak at the intake manifold. Wouldn't hurt to thoroughly clean the throttle body with a spray cleaner.

Consider the possibility of it being an ignition problem such as the coil or igniter acting up when hot.
