Rough Idle
 

Idles rough but smooth at cruising speeds on a 1987 non-turbo 5-speed. Rebuilt primary fuel injectors, and checked fuel filter, also new plugs. I am no rotary mechanic, an independent shop did the work, but they cannot fix the rough idle. Any ideas on what I can try, or do you know of a good shop within a 200 mile radius of Charlston, SC?

When car is idling take a spray can of carb cleaner or WD-40 and spray near the intake and vacuum lines. You are listening for a raise in the idle and if that happens you have a vacuum leak. There is most likely a leak in a gasket or line around the engine.
