Having problems with a hard miss every now and then, sometimes it does it pretty good, replaced coils, plugs, wires, fuel filter. Had the ignition module checked out and was good, but thats not always accurate. Just wanted some input before i go to the expense of a Ignition Module

Hard Miss Problem any input

I had spark plugs breaking on mine. The ceramic would crack but it would still fire, missing just everyso often. It happened on 3 seperate occasions, 3 different plugs. I spent money on good plugs and hasnt happened in over a year now. The plugs I had before weren't the cheapest, but I went ahead and bought the best NGKs.
