Sent to Car Experts February 01 01:37 PM

Have a 1994 Saturn SC2 and it idles real high then goes way down, then dies when it gets warm.
The oxygen sensor and throttle sensor have both been replaced. Any suggestions on what it may be? I have called to get it put on computer and the dealer says it would have to be a 1996 or newer model. Help?

Optional Information:
1994 Saturn SC2

Already Tried:
replacing the two sensors that are in my question

Here's how you can read your codes.

To extract a trouble from the computer for diagnostic purposes, the Assembly Line Communication Link (ALDL) connector is used.

Ground terminals A and B with the ignition "ON" and engine not running. The system will enter the diagnostic mode. In this mode, the computer will display a 12, three consecutive times, by flashing the "CHECK ENGINE", "SERVICE ENGINE SOON" or "MALFUNCTION INDICATOR LAMP" or light. A 12 consists of one flash, a short pause, then two flashes in rapid succession.

After 12 is displayed, any stored trouble s will be displayed by flashing the "CHECK ENGINE", "SERVICE ENGINE SOON" or "MALFUNCTION INDICATOR LAMP" light. All s are displayed 3 times each then a 12 will repeat. In the diagnostic mode, the computer will also energize all computer controlled relays and solenoids.

I was getting a code 15 but the manual doesnt show that? I was really hoping for an answer as to what else it may be that keeps the motor revving up and then going so low that it dies after it gets warm.
