My engine has developed a miss on #1 cyl. I determined this with a infrared thermometer. It started out as very slight and intermitant yesterday. It only lasted about 2 or 3 minutes and then went away. Today it was a little rough on start up and within 1 mile #1 cyl is dead. My thinking is that it is a wire or injector, maybe a plug. Engine mechanically sounds fine and oil pressure is right where it should be. Has anyone had a similar problem?
