P0302 Misfire Cylinder 2. Can it be a fuel problem?

[jhonatansc]

i have an 03 sedan. the computer read misfire on cylinder 2. the electrode was broke in the spark plug. i changed the spark plug and checked the compression and its 120. the boot was full of oil. i cleaned the boot.

also, i checked the coil and spark plug and is sparking. after that still reading misfire on cylinder 2. can a fuel problem cause this code?

Sounds like at the minimum you may have a valve cover issue that you need to take care of (the oil).

the spark plug was lose thats why i think it had a lot of oil.

The valve covers are known to have bad seals in the spark plug chamber.Does it feel like it's mis-firing?

yes it does.

I would have guessed the coil pack....so hopefully a tech will chime in.

When I had the same problem with mine, I ended up moving the coil to a different cylinder and swapping spark plugs as well. The misfire moved to the cylinder that I put the coil on so I knew that was the problem. If it stays on the same cylinder, it could be a problem with a fuel injector or possibly oil getting into the cylinder as 120 psi sounds pretty low to me.
