on the vr6 corrado i can feel the engine while i'm in neutral shaking a little, just slightly. when it's in neutral you shoudent feel anything right. this is bothering me is it the engine mounts? or something eles. I just did a tune up and everything is mint just a little taping sound from the valves but the mech said its ok thats normal. it's got about 130 000 km what can it be or what can i do???
