Depending on the severity of the misfire and the strategy used by the manufacturer for testing the engine for a misfire, the Check Engine light may be off, on or flashing angrily at us. This is one indication of just how severe the miss is but I think most of us can tell that without the CEL’s help. You can feel it. Well, if you’re an experienced technician you can. And I’m sure most of you reading this can remember more than one instance where you knew a miss was occurring but the ECM didn’t have a clue – at least, one you knew about.
Technicians have been chasing down the cause of an engine miss since the first automobile. After all, any condition that impacts the normal combustion process will result in a cylinder event that isn’t as strong as it should be – and that’s a “miss”! Even with our long time experience with this particular concern, I still see techs head straight for the spark plugs rather than perform a few simple diagnostics. Maybe it’s the terminology? Miss-FIRE?
