So far all my rough idle and poor running problems were solved with Chevron Techron fuel treatment. Its available at Walmart and auto part stores also. It happened so often with my 190 2.3, I started adding 35ml to each tank and my car has been perfect for the last 2 years. The discription of your problem is a little vauge so what I suggest is put a bottle or 2 in the car and while your trying to fix your car and it might just clear it self up. Chevron Techron..no substitutes... I wish I had a 16v hot rod in my driveway. I think were assuming your maintaince as far as tune ups is up to date.
