Vibration at 1500 rpms
When I crank her she will be fine until she hits abt 1500 rpms and will have a pretty loud vibration for a second before she drops below 1500. But if I rev to 15 it will vibrate. And ideas? Has anyone else experienced this? Ive gotten underneath her but can't put my finger on it. I can tell it's coming from the rear. Thanks. 2016 392 manual
