2001 4.6 V8 just lost power
I have a 2001 F150 w/ a 4.6 V8, just went over 80K miles. This morning the engine started trembling and the power is weak after an hour of driving the service engine light came on. The engine idle's fine but the trembling starts when I drive and the power is weak. Could it be my spark plugs going bad. I have not changed any ignition parts yet.

Coil? our trucks have those?
You can see if your getting a good spark. Start your truck and reach down with rubber gloves and pull and plug wire off the spark plug. Hold the plug end close to the plug. You should have a powerful enough spark to jump through the air and arc to the plug from the wire. This should be good for an inch or two. If the spark ain't jumping, than your not getting enough voltage.

hmmmm,
Well, I just replaced my plug wires with Taylor Spiro Pro's. They were Universal so I had to cut and crimp myself. Took me two hours.
They were regular plug wires. No coils were attached to the plugs.
The wires ran from the plugs into what looks EXACTLY like a distributor. Next to the distributor (electronic ignition) is a black box with a wire harness that comes out of it and goes into the distributor. It did not look like a conventional coil pack, and it did not have a plug wire coming out of it and going into the distributor. it had a wiring harness instead.
I guess you could still call that a coil. However, when I hear the word "coil". I think of the old fashioned round coil packs. You know, the ones Accel makes and so forth.
I know I do NOT have 1 coil for each plug, that's for sure. If we still disagree I can take some pictures with the digital camera and post them in my gallery.
