Has anyone had any experience with a rough idling on a 1993?

Yes. New plugs and wires. Good TB & IAC. cleaning. Run a bottle of Chevron Techtron thru the tank and she never ran rough again. Maybe this helps your idle also.

Hello.
Look for vacuum leaks first! Like the hose going to the vacuum canister under the D/S head light assy. Or injector o-rings leaking.
