Just replaced Plugs in my PA-28-181 with Tempest Fine Wire(UREM38S) and seems like engine is running rougher then with the Champions i had before fine wires installed. Mag check (on Fine Wires) runup is fine (good mag drop). And in flight its been running rough(Vibration). Changed all Fine Wire Plugs to Tempest Massives 2 days ago and know running fine on mag check and in flight. Just checked resistance on Fine Wires and 2 of plugs less then 3hrs show nothing(open) and other 6 are 1000 give or take (Did not check resistance before install which should have) Maybe plugs were bad before install? is there someone i can send these plugs to get checked out? I did contact Tempest to possibly send them back, just waiting for there reply.
