Any thoughts?
Mercedes, E420 1997
Yesterday I got off the freeway and noticed rough idle also in neutral and park, after 2-3 mins got "Check Engine Electronics Message"
I read the codes at the local autozone and here is what I found out:
P0170 "Fuel Trim Malfunction (Bank 1)"
P0173 "Fuel Trim Malfunction (Bank 2)"
P0455 "EVAP Emission Control System Leak (Large)"
P0306 "Cylinder 6 Misfire detected"
Has anyone else have this problem and is it something which I can fix myself or its better to take the car to mechanic?
Thanks for your help

PO455 is a fuel tank pressure sensor. I don't know much about that.
PO306 is cylinder 6 misfire like you said above. I am no expert but I would check your O2 sensors, plugs, and coils.
I hope you are using premium gas.
good luck!
