im having this really big problem with my car... it started a couple days ago and all it sounded like was a cylinder misfireing.... so i decided that i would do the plugs and wires... did those and it ran fine that night after i changed them... but then today it started misfireing again... and the weird thing is that it is just doing this when the engine is warmed up... i have no idea what it could be, maybe just the distributor cap and rotors... so im gunna be doing them saturday... could it possibly be the ignition module?

 

Prolly the Optispark.

 

damn... how much for a new one, and is the opti hard to get too?
