94 Saturn SC2
Just " inherited" this car from my daughter as a pay back for a loan I gave her. The car seems to start okay and it seems to idle like a cold car would normally idle, I believe, about 1600 RPM. But, then, the idle seems to go down sharply to a normal idle of about 700-800, but it does not stay there more than a few seconds. The idle then begins to fluctuate between a high idle and low idle (800 - 1600 rpm) over and over again and does not stop the fluctuation at any time. When I push the accelerator, the engine does not respond. Instead, the car chokes and dies. And then it will not start again (engine turns over but will not start) until it cools down completely.
This car has a history of running hot, so I am told. I tried to check to see if the electric fan would work. Turned on the ac, but the fan does not seem to run when the ac is going or at any other time.
Someone told me to replace the ECT sensor (also called the PCM Temp sensor). However, I am seeking other opinions before I go buying parts for this old car.
