Optispark is the distributor, sends spark to the cylinders.

if it's cutting out, sputtering, dying, etc it is probably the optispark. It is located underneath and behind (sort of tucked actually) the waterpump. To replace, the radiator, air intake system, and waterpump come off and there she blows. For the cheapest route, you can get a new OEM piece from samtaylor.com for something like 239 shipped.

The biggest problem with the opti is NOT the opti but rather the cap and rotor cost more than other distributors and are harder to change so people neglect them and they cry when they eventually act up but ANY distributor will act up eventually if the cap and rotor are left on as long as many are on the opti. Is it perfect no but it's reputation is FAR worse than deserved mostly because people lack anything resembling reasoning skills these days. Other distributor caps and rotors are frequently changed with the plugs and wires because they are a wear item due to the spark having to jump the gap from the rotor to cap.
