I tested my coil packs with a meter. I wasn't really sure what the numbers told me, but found out that none of my coils were bad.....
Here is my post, and directions. As it turned out, I had a plugged cat converter, after blown head gasket. You might have a muffler shop test your exhaust pressure. Crazy sounding I know.....cat converter causing po300, but that's what it was.
