You'll really have to be a little more specific. If your driving down the road and come up on a slight hill and your car didn't downshift and your RPM's are around the 1200-1500 mark and it aquired a slight miss/hestistation then i'd say change your fuel filter first as a possible fix and a preventative maintence. Also pull a few plugs to see how they look. Also plug wires is another possiblity.

wow you just jumped from the frying pan into hell I'd say do some smaller simplier things that can cause a miss before forking out 500 on a MSD opti. Its probably just a clogged fuel filter, wire or plug.

Shh, I wanna see his reaction when he replaces it with 500 dollars of sweat and blood, only to still have a miss! This is better than Survivor!

why do people always jump to replace the most expensive part of the ignition when it could be the $4 spark plug.

Because when it comes to changing plugs, or changing the opti...price is no longer a factor and people start shoving money down the throttle body at WOT in fear.

Honestly, changing an opti to me is easier then doing a plug wire change on a LT1. Passenger side is doing a plug wire change is BRUTAL.
