Car will only start when gas pedal applied, when gas pedal released car stalls on 1992 Toyota Corolla

I have 1992 Toyota Corolla and it will not start unless I apply the gas pedal. As soon as I release the gas pedal it stalls out. I was hoping that adding some heet to the fuel tank, any water that may have built up would evaporate. But, it seemed to be no help. Where should I start to try and find out what's wrong. Thanks.

idle air control motor or throttle body. have them checked to verify.

if this car is automatic, it may be the lock up solenoid in the transmission. when it sticks, it lowers the idle to a stall if not driving.
