I have a 93 SC 400. Recently had timing belt service, new fuel pump, new steering rack, plugs and wires. Car is solid and runs great, however.... recently it has started to feel like a misfire every so often during idle. It's not so bad that the car feels like it will stall just a slight misfire occasionally. Once I accelerate from idle the car runs great.

Any ideas?

Was it doing that before the big service you just had done? If not take it back and say something. It's probably something simple.

Wasn't doing it prior to the service but it didn't do it for about 5000 miles after the service either.

Check your coolant. Mine was nasty and filled with rust. Cleaned it out and filled it up ran like normal.
