CHECK THE TIMING
12 volts with the engine off. 13.5 to 15-5 volts with the engine idling.
Have your sensors checked.
Check the sensors, mine did the same thing and it was the sensors
The idling speed cannot be adjusted for fuel injected models. It is done by the ECU depending on inputs from various sensors. If the idling is erratic it is best if the car is taken to the vauxhall dealership who have testing equipment called TECH 2 which diagnoses the problem.

Check your grounds, wiring & plugs to start. The grounds on the engine are a good place to start
Idle speed is set by the engine control computer, if yours is too low it has to be caused by an outside source, check for air flow, air flow sensors, throttle position sensors, or a dirty throttle body.
A car that is stopped with the engine running.
The 1987 Chevrolet Corvette oil pressure should be between 45 PSI and 40 PSI. The idling oil pressure will be slightly less.
The idle is not adjustable.You have other problems if it's idling to fast are to slow.The throttle plates are calibrated / preset at the factory.Is the check engine light on ?? If it is, then you need to have the engine scanned with a engine scanner to check the emission system and sensors. It will also help your idling problem after you repair the problem that made the check engine light come on. If you don't find your problem in that area. then PLEASE ask your question again.

water in the fuel can cause an idling motor to sputter and/or die.
There are two temp sensors on this car. Basically the have the same function,just for different parts of the engine. The one you need controls engine component Via the PCM(engine computer). It is located on the right side of the block around the top hose. Look for the two wire harness, for the sensor is sort of hidden. Remember there are two sensors, but i believe you need to upper one. Hope this helps
