Hey, I own a 2000 V7 STi, and on my way home from work today, sitting in traffic and rain, there was a consistent double knocking noise, and in the time between both knocks the RPM would drop 250-500. If it were just the knocking noise I would just assume it would be something with the suspension/shocks. I have to go see my mechanic tomorrow anyway, but thought I\'d ask here to see what anyone thought it could be?!
*It did this after I first bought it(6months ago) but stopped on its own accord, so didn\'t bother me.
*noise from what i could hear from driving was coming from back left ..
THANKS!
