My truck had just started to bounce in reverse and when its ideling it bounces also but not much. At also does in when I'm accelerating. It feels like the tires don't want to spin and they are slipping but its not because I had a friend watch the tires and non of them were slipping. It's not a hug bounce its just a slight bouncing motion and you can't notice it from the outside. If you need anymore info just ask. And I just discorver that there is an exhaust leak coming out of the muffler were the seam is going down the muffler. Such a great day (not)

Also forgot that I just drove through some mud yesterday that had a bunch of rutt's that I didn't see or it could be from some mud clods

Misfire on cylinder 4

Does the steering wheel shake?

I<3myFord

No steering wheel does not shake

Uh...take care of this first. Get a new cop or move that one to an easier to reach cylinder and see if the misfire follows.

Misfires cause weird things to happens and it's hard to tell if your little bounce is related.

I think they might be related hopefully. Im going to change the plugs and wires this weekend. This is going to sounds stupid but what is a cop?

Tackle

A cop is what goes on the plug, depending on the year if it doesn't have wires.
