My 1996 E320 started running and idling rough a week or so ago after a thorough car wash that included a very careful under hood cleaning. I realize how water can affect certain components, so I was very careful. Autozone took a look at the engine codes for my. They are:
PO441 Evap Emission Purge Flow Fault
PO302 Cylinder 2 misfire
Any thoughts on what I should do or look for? Thanks much.
