you cannot test at home.it takes a machine that runs a spark to the plug while you gradually increase pressure.if its bad,it will not fire in the 80+lbs range.HOW TO CHECK IF SPARKPLUGS ARE BAD?
Bad plugs almost always show up as misfire under load. You will find a particular point on the throttle (varies with the incline of the road and engine temperature) where the engine power actually drops and the engine runs rough if you go past it, then comes back when you let off a bit, just like there was a switch doing it.
You don't mention make, model, or year, and power loss problems often depend a lot on that.
