Sorry, SES is what I meant. SIS is for Suffer In Silence and I only use that when I want to give my wife a hard time. I don't know about the performance wires, but I do know form experience and many others on this forum that AC Delco wires are the only proven wires. As for the distributor cap, looks can be very decieving. You're better off just buying one. The design I like is the Echlin brand from Napa. The plugs should be a good platinum or AC Delco at a minimum. Bosch works better on more intense ignition systems and foul out easy on the 4.3. Does it always stumble / surge after you start it cold or is it intermittant?
