Default How do I test for bad coil pack

I believe I might have bad coil pack. I have mutimeter that will can test for ohms how do I set that up? I have replaced plugs and spark plugs. It still seems to have slight miss fire

Techinfo. Do it hot and cold (use the oven if you have to). Some coils fail only when hot.

My best advice is to find a donor car and borrow three known good coils for a short troubleshooting session.

Ok Fixed as usally with my car it was some stupid I found that my new 6 cylinder plug was cut put the old one it sort of happy but still missing some times. So I took coils off and clean the connection. Heavy deposit on mid coil. For now it seem to be happy
