Question about 1986 Oldsmobile Cutlass Supreme

1 Answer

Carb loading up and engine surges at idle

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.

Can you please tell me where is the turn signal flasher on a 1986 oldsmobile cutlass supreme brougham


On 1980 and later models, both the turn signal flasher and the hazard flasher are located at the lower left hand and the upper right hand corners of the fuse block respectively. Remove these by pulling them from their connectors.
The lower dash panel may have to be removed to gain access to the unit.

2008 Ford Edge engine surge while stopped in gear


Sounds like a faulty Throttle position sensor. Warranty should pay for parts & damage, talk to your dealer. The 88 -90 ford tempos had same problem & a driving school was using them, lots of kids & instructors got the heck scared out of them, but luckily no-one injured badly.
