All,
I noticed an odd vibration at idle today. When I depress the throttle and slowly bring the RPMs up from idle through 1200 I can feel a funny vibration. This vibration does not show up when driving but does occur in both park and neutral. The truck seems to be running fine other then that. Let me know if you can think of anything that might be causing this.

Thanks in advance for the help!
John

 

I've got a similar sig. to yours with the same slight vibration. I have had to the dealer 5-6 times. One time they found that the exhaust was touching the frame and readjusted. Other times they told me nothing was wrong. It has been driving me crazy trying to find it.

 

Alaskaworktruck,
Thanks for the quick response!
I will check out my exhaust and see if that is the problem but it is all stock except for the muffler. I am going to take it in to the dealership for my free oil change and ask them about it. I hope they can shed some light on the problem.
