I see what 99grandprix is saying. A dead injector at idle would have way to much fuel to fire so the idle may not change. Of course low compression will do the exact same thing.

I guess this is a possiblity. Who knows, maybe you won't have to pull the head. But I don't think extra fuel in the cylinder would drop the compression from 170 down to 60psi.
