For the past 3 weeks I have been trying to sort an extremely rough running 190E 2.5 16V none CAT model. The original problem was rough running on idle and high hydro carbons. All the obvious, such as air leaks, plugs, cap, leads, rotor arm, valve clearance, valve seats and new injectors, have no difference what so ever. I'm tearing my hair out over this now!!
