Question about 1995 Saturn Sl
Car starts when cold,can run car for 100 miles works fine until you shut it down.it will run until you touch gas. fuel pressure is fine,changed crank sensor,temp. sensor.1.9 single overhead cam
Blair, I would take a look at he TPS (throttle position sensor) located on the throttle body. In other words, it sounds as thought sensor when heated is changing its value to "open" or "shorted".
If the car starts OK when cold, use a hair dryer to heat the TPS when the engine is cold to see if you can duplicate the problem.
Also is the a service engine light on? Codes?
If you have a "digital volt/ohm meter" available you can read the variable resistance of the sensor when the problem occurrs to determine if the sensor is defective.
