Hey guys, I discovered a fix to an issue a lot of people seem to have so I thought I'd post it up here for anyone in with similar issues. I had a pretty nasty gas pedal vibration that never seemed to go away. I went through various stages of thinking I was being nitpicky or overly critical but it did bother me. I tried a few fixes to no avail and then one day when I was under the truck I remote started it and found the exhaust leaking pretty badly at the joints (I know that water is supposed to escape but I could feel exhaust escaping as well) I bought some JB Weld exhaust putty and patched everything but the weep holes and the vibration is pretty much gone altogether and the truck is a lot nicer to drive. Just putting this out there for anyone who may have a similar issue.
