20 Most Recent 1983 Oldsmobile Cutlass Supreme Questions & Answers


Worn out gauges would be the first guess. The next would be the oil pressure sensor....

The gas gauge could have problems from a bad float in the gas tank or the wires to the sending unit are badly deteriorated.

There's a chance the cam and crank gears are not in line with each other. You could try placing the rotor 180 degrees from TDC and see how it does.

Well, you know the ignition coil has to be good. then the ignition control module inside the distributor has to be good. It controls the ignition coil firing times. This module can be tested at a parts store. And then, also in the distributor and attached to the ICM is the pick-up coil which tells the computer crankshaft position, so the computer knows when to signal the Ignition Control Module that it is to cause spark out of the coil. These are the components of the ignition system, so you know how to check them. Ignition coil, ICM, pick-up coil, and the pcm, computer.

First, check that power is getting to the coil when the key is turned to on. The coil must have battery voltage applied to it before it can cause spark. If there is power there, test the ignition coil, test the ICM, then the pick-up coil. If your wiring is good, one of them components may have failed. And of course, the last thing to suspect is the computer, the pcm. Hope you don't have to get that far.

black spark plugs indicate a rich fuel mixture and that is a carby problem. If you are running a holley then check the power valve as they have a habit of cracking or failing after a few back fires and this will allow excess fuel to by pass the main jets and blacken the plugs. Check float levels and air filters.
