trouble diagnosing code p0302

Question

Replaced cylinder 2 coil, all 6 spark plugs, engine light still blinks when idling.  Compression test showed cylinder 2 was about half of the other 5 cylinders.  Put a little oil in cylinder 2, did not raise compression.  Any advice or should I just mention all of that to the dealership and make an appointment?  182k miles but still looks and drives great except for idling and occasionally a hickup starting.  I assume all of my fuel isn't burning because there is a stroner than normal fuel smell at idle.

Answer 1

P0302 Misfire number 2 cylinder

If the compression is low about half and you add oil in the cylinder to bring up compression but remained low, you have cylinder valve problem as for the fuel smell the fuel injector can be leaking or the fuel pressure regulator can be leaking, the danger about this is having raw fuel smell which can be from any place where the fuel is distributed.
