Question about 1986 Oldsmobile Cutlass Supreme
I have a 1986 Cutlass Supreme Brougham. The car was loaned to a "friend" who in my absence decided it needed a tune up. when i got the car back it would not run. I have replaced the incorrect spark plugs, plug wires that they laid on the exhaust manifold, distributor cap, rotor, and carb that the fuel inlet filter housing was stripped out. the car will not run above idle without the carb loading up and dumping fuel into the engine. The idle speed surges. is there a control, or vacuum module that i need to address? This is a 307 Olds Motor with a Rochester 4bbl and auto tranny.
I called an old mechanic friend who confirmed what I suspected. The engine control module which controls timing was the culprit. I replaced the defective unit, and the car runs like new.
