1900 RPM=Violent fr. to re. shaking while driving
 
This happens right around 1700-1900 rpms in basically any gear. It dosent feel like a normal vibration just a front to rear shaking. The engine is stock minus boltons. It does have a b body cam/short block in it on the stock tune with roller rockers and a lt4 km. The flywheel has also been replaced with a really cheap autozone one. Whats weird is it dosent happen all the time, but it does almost always happens when its cold.

Dirty MAF or bad plugs, maybe 02s went bad
