it also has no power at WOT(revs up like its tied to a tree) and my predator programer shows a #8 misfire but no check engine light. Also my battery is going I believe(turns over slow on a cold start). I'm thinking a bad coil. If so, is it worth replacing it with an OEM or should I just get an aftermarket set and be done with it. The car might see a blower in the future.
