#1 I can feel the vibration in the shifter and siting in the driver seat or against the body
#2 The vibration can be felt with the Clutch pedal In or Out
#3 Vibration is always there like the engine is runing rough, can be felt through out the whole rpm range
#4 If i put my hand on the crossmember, A-arms, Front sway bar is smooth as silk. No vibes there.
#5 With the splindle sleeve that engages into clutch pulled back( not engaged) the vibe is still there.
#6 The car runs fine, with no noticeble loss in power, or Oil pressure and good temps
#7 No codes on the DME, Good voltage power, O2 sensor reads right
