Hope owners club can help. Started to get a misfire on my way home from work today  :'(. Engine warning light came on and went off. Problem is very intermittent. Plugged in the ODB2 reader and got a P0304 code, so misfire in cylinder 4. Will check plugs and swap ignition coil retest tomorrow. fingers crossed. If its not that I'm assuming injector? Any ideas and thoughts gratefully received.
