: Idle Surge 1992 Brougham 5.0

11-20-10, 03:22 AM
I recently tuned up my 1992 Brougham. I replaced plugs, wires, pcv valve, O2 sensor, fuel filter, air filter,distributor cap, rotor button, and cleaned the coil.

Lately, I have noticed that after starting the car, driving it, then shutting it off that I have idle surge after re-starting. If I shut the engine off and re-start, it takes care of the problem.

Any ideas what might be causing this idle surge?
