Did you put in Bosch +4's?!!!!!!!!! That's your issue. Get those things out of there. Get some Autolite APP764's or some Champions. Plugs need to be double plats. IMO the only reason the Duratec misfires is poor plugs and wires. It might like one brand and not another. Seems to be touchy to certain combinations.
