Engine is fine except at idle at operating temp. Then it's just rough enough to be annoying but not rough enough to throw money at it. Been this way for the last 15K miles. Dealer did a tune up 10K miles ago and said there's dirt in the fuel distributor. Can it run so smoothly at anything but idle for this to be possible?
Oh, starting is a little difficult. Takes a while to catch, then stumbles for a few seconds before stabilizing. This happens at anything from hours to days after the last run. Warm restarts are usually not a problem.
While I was in the area, I checked the idle switch. Continuity at idle, open off idle.
