Your local autozone can rent you out a compression & leakage tester. Id go that route first.

^^ what he said above. If the compression numbers are good, then check your coil pack housing. If it looks burnt up or cracked. (theck the springs in between the coils and coil housing as well) then replace it. You could also check continuity across the 4 terminals just to make sure.
