hey everyone just wondering if anyone can help me i have a 93 wrx and whenever i drop the clutch or lift my foot off the accelerator i get a grinding / rattl noise only between 2000-3000 revs and sometimes on acceleration, you can feel the vibration through the gearknob when this happens. any ideas what this might be???? thanks

 

one of the exhaust heat shields maybee? one of mine made that noise until i rammed a bolt into it!

 

yeah i thought it might be a heatshield but i have checked them all and they seem solid no movement im puzzled??
