Why does it run without the cops?? It has wires that run down to a four terminal distributor on the front of the head and has the same thing on the other side. All of the wires are the same. They have a big boot that is flat on top and the wire runs into the side of it close to the top. The boot has a flat top that is shaped like a 3/4 moon.

 

What I meant to say is what do I have here?

 

You have 2 coil packs. 4 cyl. each. COP's do not use coil packs and there is a coil on every plug.

 

So am I supposed to have COPs or not? Do I have the right wires on it? I am confused ( which happens frequently) as to what I have. I have seen the COPs that ya'll have talked about and I thought I was supposed to have them on the 4.6 that I have but I have the coil packs and the wires with the big flat headed boot and NO COPs. I need a history update on the FORD engines. Been a long time since I worked on one (as you can surely tell). Can you give me a brief (or not so brief If you wish) lesson on what I have and why I have it? :-)

 

I don't think the 4.6L trucks got them until 2000. You should have coil packs with plug wires.

The 5.4L trucks have had them since 97.

 

Good then, I have the right equipment for the right year. Scared me there for a while. Thanx to all for the answers. Now for the prize........Whoever said plug wires gets the grand prize: An "I LOVE CHEVY" bumper sticker.
