Question about 1986 Oldsmobile Cutlass Supreme
The light is on because a problem exists in the engine electronic controls. To reset the light disconnect the battery negative cable for 5 minutes. If the problem is still there the light will come back on. In that case you need to run a fault code test on the system, to do that go here and read the way it is done.

I am having a similar problem, but there is no check engine light. It seems that mine dies at the light or running, if the rpm's drop. I am wondering if the Idle air control valve is bad or possibly the ERG valve?
