OK , Just bought a 2001 Focus 4dr with the 2.0 SPI and an auto trans , Only gave $750 for it for my son as a work beater ,the issue is a drivetrain vibration at idle and while driving it seems like it is rubbing or resting on something , going over bumps and dips on country roads seems to make it come and go but it never really goes away , the mounts seem fine but maybe it is something else ??? Any ideas ????
