Good point. Thanks Wrenchtech. Unless your mechanic is a real dummy, he will probably switch two coils to see if the problem goes to a different cylinder. The same can be done with two injectors but it takes a little longer.
Normally if compression is the problem, there's going to be other symptoms besides just a misfire. For sure if it's an intermittent problem, it's not compression-related because anything broken or worn won't fix itself once in a while.
