2000 F150 Spittin' and Sputterin'
My 2000 F150, 4.6 V8 is spitting and sputtering. Idle is a little rough, but seems to even out at highway speeds. My first thought was plug wires, but I looked under the hood and I don't have plug wires! Any ideas or thoughts would be appreciated. Thanks. -Al

Light came on - definitely a problem with the #8 cylinder (figures). I changed the boot first, and that didn't fix it, so I changed the plug. It's still misfiring - BAD! I guess the only other thing it could be is the C.O.P. right? Is it possible I didn't put the new boot back on right? Is there more to it than it seems? I just put the spring on the COP, slid the boot over that and bolted the thing back in. The resistor on the plug looked fine, but the plug itself looked really bad, although I didn't see any cracks or anything else. Anybody got any ideas before I spend $50 on a COP? Thanks. -Al
