If you had a 4.6 originally, you have coil packs and plug wires. If you had a 5.4 originally, you have a coil on each plug. Which do you have?

how do I check the circuit

I've got the same problem.

When I wiggle the wires the truck runs rougher. But I'm not exactly sure Wich wire or where it's broke. Can you post a pic, or describe how you fixed it? Was it in the connection to the fuse box or in the wire itself? Tnx if not I'm sure I'll get it.

O2, the OP only posted three times TOTAL and hasn't been back in a year. You're not going to get a reply from him. You need to start a new thread if you want help.
