Engine codes on my c280
I pulled the following codes yesterday.
P0442 - Evaporative Emission Control System Leak Detected (small leak)
P0455 - Evap System Large Leak Detected
P0170 - Fuel Trim Malfunction (Bank 1)
P0173 - Fuel Trim Malfunction (Bank 2)
I cleaned the area around the gas cap to ensure a tight seal and then disconnected the negative battery terminal to clear the code. Today the check engine light came back on.
I have also listened under the hood for a vacuum leak and haven't heard anything. What should I do next?

MBWorld Fanatic!
fix this? there is another post around here that talks about the possible issues with this. run a search on p0455 but i think the post said there were 4 possible things to be replaced. let me know if you cant find it.
