Gas Pedal Buzzing/Vibration

[hotrodz37]

Hi All,

 

I have searched the forum and didn't find anything related to my problem. Most people with the vibration in the gas pedal said it was not speed or rpm related. I started noticing this a pedal vibration/buzzing a few month ago and tried to let it go but now it is driving me crazy. I started noticing this when I got new tires, maybe it is just a coincidence which I do think it is. Let me first start by saying the tires are perfectly balanced and no vibration anywhere else in the truck so to speak, but wondering if the new tread design creates the tiniest road resonance but hard to believe the new tires would cause that since they are smooth as silk. Mine started off at about 45mph under load. Since then the range has broadened and now the pedal buzzes from 40-50mph. I tried tightening some of the bolts and brackets around the pedal and it helped a tad but since is just as bad as before. Are there any others experiencing this? Any help/solutions would be greatly appreciated! Thanks!

If the vibration comes and goes, it might be your AFM. Mine did that until I started using the Range disable device. Try driving in M5 & see if it still does it.
