2001 Mercedes E430 & 1993 Mercedes 300TE 4MATIC Wagon
Ok, so we finally decided to get our drivers side catalytic converter fixed tomorrow as well as the oxygen sensors. (Car is at 107k miles)...so Im wondering if fixing this would fix some rough idle, lower gas mileage and performance issues??? Does a rattling cat converter really influence all of this or is fixing it a waste??? What does fixing the converter fix specifically???
