Hi everyone thanks for the replies and help-
It turns out it is either my IAC valve, or the black box (I think it's a filter) that is right before the IAC valve. I too, thought it would have been the intake, but I took the filter and the housing for the filter off and the car still did it. While the car was making the humming noise, I squeezed the tube going from the intake to the IAC valve, and the car stopped the humming.
However upon doing that, I realized that my intake filter and intake housing is totally shot. The upper part of the intake before the filter is completely fine. The black cover is all cracked and warped (not a perfect circle) so the intake can't get a good seal. Stupid previous owner!!
To fix the intake problem, I was thinking of buying a JLT Next Gen intake because I can't for the life of me find OEM parts for Bullitts!! Do you guys know of any sites that have OEM parts?
I'm also looking for replacement shocks (currently has shot but stock tokico's) but can't find Tokico's like on my Bullitt. I was wondering if there is a reason for that? Are they not good? Could someone lead me to a better shock out there?
I want the car to perform the best it can at the autocross and on canyon roads. I don't care about ride quality either.
So I guess I leave the post with this shopping list:
1.) IAC Valve
2.) Cold air Intake or OEM Intake if I can find one (help!)
3.) Replacement or stock shocks that are built for autocrossing (help)
If you guys could lead me in the right direction here it would be much appreciated!
