Hi! I have a December 98 MB A160 Avantgarde.
I seldom use it, thus my present mileage is only 6,200 kilometers (3,800 miles). I am quite puzzled bcoz my car exhibited rough idling a couple of times during start up. Sometimes it happens, sometimes not. So whenever it does occur-I dont use it. Then when i start it up again after a few hours...everything goes to normal. Please help! Once I saw fuel spewing out of the gasoline sensor adapter nut, so i simply tightened it...but the rough idling still occurs.
