OLDSMOBILE CUTLASS GAS PROBLEM

1991 Oldsmobile Cutlass • 218,000 miles

What happens when the RPM guage jumps up and down when idling and sometime the motor dies. Sometimes when stopping at a traffic light it will die. The car is supposed to use reguler gasoline but has been using gas with alcohl. Will this cause a problem.

Yes, it could.

It could be a vacuum leak, idle control motor, egr valve open or fuel pressure regulator
