Vibration and noise at 1200 rpms
finally pin pointed the problem I have been complaining about for months. this vibration and noise occurs when the engine is steadily at 1200 rpms whether its in park or drive or reverse.....it is more pronounced when in gear......anybody have any idea or clues
OK, I know this is an old thread, but someone searching the forum with the same problem may find it in the future. I had the EXACT same buzzing/vibration problem with my '08. Drove me nuts. It was at 1250 rpm, worse while the truck was under a slight load like going up the slight incline in the parking garage at work (everyday) or driving up the road to my house (everyday).
Went on for months. On this forum found answers about bad torque converters, faulty MDS, U-joints, heat shields, and other answers. Turned out to be none of the above and I was able to fix it for $4.
Turned out to be nothing more than a loose clamp on the exhaust. Specifically, the first one after the pipes leave the engine and come together and start the long run back to the muffler. Right about under the front passenger's feet. It wasn't loose enough that it would move by hand, just enough to produce a different tone if you banged on it with the heel of your palm.
The original clamp was rusted solid, so I just put another 3" clamp behind it and the problem went away entirely.
Hopefully this will help the next guy with the same problem. Sometimes, the solution is simple and cheap.
