My car has new plugs and wires new coil wire none of my wires are burnt but at around 5000 rpm and high i have like a studder. my car went a 13.5 last week and tonight it ran a 13.8 same track conditions but my car studder and at high rpm in every gear. What could this be? Could this be my coil? If it is should i get the MSD one? my car has 73,000 miles and i am HOPEING this is not my opti! thanks

Just replace your coil and coil module, they the coil is like 15.99 from Autozone, and I think the coil module is the same price.

It will definitely help you narrow down the problem. As far as ignition goes it really can only be coil, coil wire, coil module, opti, plugs, and plug wires. Just replace everything start with coil, and coil module, then plugs and wires. Then opti.
