2002 Mercedes C320 Wagon
![Question](https://mbworld.org/forums/images/icons/icon5.gif)
So I have had a rough idle in my car for a long time and I have been trying to solve it but have been unsuccessful.
Only does it when car is in gear.
So far I have: (Underlined = within last 6 months)
Car has 180k Miles
Cleaned maf
Replaced Rubber Gasket things in the Intake System connecting maf to intake elbow and to airfilter box
Replaced all vacuum lines
Replaced Fuel Filter
Replaced Fuel Cap O Ring
removed throttle body and thoroughly cleaned all oil residue and replaced throttle body oring.
Replaced Spark plugs with NGK Iridium
Replaced Spark Plug Wires with Bosch Set
Replaced Air Filters
Engine Mounts Replaced (2 Years ago)
Transmission Mount Replaced (2 Years ago)
Also replaced Transmission Filter, Gasket, Transmission plug and did full 12qt transmission flush using transmission coolant lines. Also replaced Valve cover gaskets and breather cover gasket.
Car is also throwing No Codes except for a EPS Visit workshop error, My traction control still works so i've been putting that one off.
I am at a loss as to what else I should do short of replacing the injectors. Maybe You guys can shed some light on what might be going on.
