Back sometime this last spring someone said that my SC2 was running like crap when it was cold because the coolant temp sensor was bad and that I should change the PCV valve right away too because these things are notorious for going bad. Well I just changed both of them today and what a difference! I drive the car last night and vowed I would get it fixed one way or another. I never drive the car so I never imagined how lousy it would rumble when cold and purr when warm. So I owe a thanks to who ever gave the advice I didn't heed until today!
I had suspected the Torque Axis Mount but the car was smooth when warm and didn't seem to be separated. Oh well....thanks again!
