This vehicle runs fine until it reaches about 110 degees, and then has a dramatic loss of power with some surging. Fuel and air filter changed. Determined to be heat related. Put 1K ohm resister in coolant temp sensor circuit to make the ECM think the engine is cool and the car runs great. Replaced temp sensor, but problen still there.
