Not sure of mileage, but sometimes I get misfire code and at other times no codes I clear it. Rough at idle no smoke new plugs. Seems to run good going down the road but a idle rough but not always.

Clean the IAC valve and the throttle body. Also check for a vacuum leak. Doesn't take much to cause the IAC on that engine to get sticky and cause idle issues.
