so my 03 6spd has a weird clicking sound only when the rpms are coming down. doesnt matter what speed im going, anytime the rpms are coming down, the sound clicks until it reaches idle. or when im cruising at low speeds in parking lots. very annoying sound. i though it was the heat shroud but i got that re welded on as well as my heat shield. then some dude said it was my intake manifold. i ended up selling the car because i didnt wanna put any more money into it but im so curious as to what this sound is as i had the car for 6 months and it bothered me waay too much
