well my high rpm miss is getting worse....its got new plus, wires, and i switched my msd coil out for the stock one and its still missing.....i guess its got to be the opti eh? but whats crazy is that it feels like its missing on ONE cyl. not all of them...

 

Well why don't see if it is indeed only one cylinder. If you had headers it would be a piece of cake to see which one.

Don't forget you need fuel spark and compression to make a cylinder fire. You keep focusing on spark.

Capish?
