Hey, I'm new to the forum and have a question about my 07 Silverado. I get a vibration around 1200 to 1300 RPM. When the RPM goes any higher it stops. Doesn't seem to matter what speed I'm going. I can feel it in the floor a little, but mostly just makes noise. Also if I put it in drive and hold my foot on the brake and hit the gas to and get the RPM up to about 1200 it does it then too.

 

What kind of noise is it making? Does it sound like it's something coming from the engine, or is it more just like your cab or dash rattling? Does it do this when you're in neutral or park too?

 

It's a low tone vibration sound. It's not a rattle and it's not in the cab. I just tried it in neutral and park. I hear and feel a light vibration at the same RPM, around 1200 to 1300, but not as bad when I'm driving. Thanks
