1996 Oldsmobile Cutlass Supreme Stalling - Engine
Question: My 96 Cutlass Supreme has 140, 000 miles. At about 100, 000 it would stall when in prolonged traffic, now it stalls at different times while driving, usually at low speeds and at intersections. It takes 5 minutes to start again. I have had all types of sensors replaced and of course the computer never shows anything and it never happens when the mechanic has it. It is very infrequent, 2-4 times a year, but I am afraid to drive it far and alone at night. I use 89 octane gas, the valves knock with the lower octane.
