Check sparkplug, compression and injector for no.2 cylinder

Engine Misfires can be caused by worn or fouled spark plugs, a weak spark (weak coil, bad spark plug wire), loss of compression, vacuum leaks, anything that causes an unusually lean fuel mixture (lean misfire), an EGR valve that is stuck open, dirty fuel injectors, low fuel pressure, or even bad fuel

Well it turned out to be 2 head gaskets, which caused problem with plugs and coils.

Thanks for the help
