Just wanna get every idea possible on what this could be. It's not throwing a check engine light.. so I can't use a scanner or other machine to determine it haha.

When I idle I'm at about 500-700rpms and it vibrates the truck... more so now that I got my pipes done then before, but I don't know why... I was thinking plugs but want other input also.

Then I also get a small vibration when going down the road but it could be because of the pipes roaring,possible misfiring going on with plugs, and of course the low tread tires, which will be replaced as soon as my new wheels and tires come in .

No one else have these problems? I really would rather not take this to the stealership lol.

Have you tried reading the rough idle/bog down issue sticky about the foam insert around your air filter housing? Also have you looked at your driver shaft, and checked to see if your exhaust if secured to the truck?

I haven't checked the air filter housing , could it really cause this? Also I watched them put it on, but that's not to say it hasn't rattled loose. Going to check both these right now thanks!!

Is that foam thingy in the 4.6 or just the 5.4 I can't find what the sticky was talking about
