My 1995 Mits Eclipse RS has a studdering problem, when your driving it will jerk or hesitate for a second and the check engine light will flash on like the engine is trying to die for a split second. Also sometimes when it is idling it will stall out. I have changed out the spark plug wires, spark plugs, done a full tuneup except for changing the fuel filter. Anyone have any Ideas or advice?

I have taken it to the shop, but the engine is not storing any codes when the check engine light comes on, I cant figure it out, otherwise it runs perfect and gets great gas millage.
