Missfire?

My truck is missing and i cant figure out why.
Every since i changed the plugs it has missed,I thought it was the coil pack so i changed it and still has not fixed the problem.

Only thing i have replaced is spark plug wires.

Any Ideas?

Have or haven't replaced the wire? That could be the issue.

I agree probably the plug wires.....But, what brand plugs did you install?
If they were Bosch, that is your problem.........

Nope not really. I still have Bosch plugs in my truck and after 55706 miles I have had no problems with them.

Right choice in plugs!

The next thing to check is to see if you crossed a couple plug wires. The coilpack will have the cylinder numbers each wire should go to, and the cylinder numbers go 1,2,3 (front to back on passenger's side), and 4,5,6 (front to back on driver's side).

I yhink you may have a bad plug.Your problem started when you changed the plugs.Start there first.
