Hello and thanks for using Just Answer.I will try my best to help you with your question.


The P0304 and P0305 are for miss fires on cylinders #4 and #5.

The code P0455 is for EVAP Control System Leak Detected (No Purge Flow or Large Leak)

There is not a common thread for all 3 codes.

The misfires are for the coils and plugs on cylinders 4 and 5.

For the P0455, check the gas cap and make sure it is tight and clicks.


But check the spark plugs on cylinders 4 and 5. #4 is on the passenger side near the back and #5 is the first one on the drivers side of the engine.
