So today I was adjusting my idle screw because my idle was a bit high after my whale intake..

Did it the correct way... engine warm and unplugged IACV and then adjust screw.
Checked idle was around 500 so plugged it back in and idle was above 1100/1200.
Switched of the car and reset ecu.

now I have a weird low buzzing sound -.-'

When I unplug the IACV you don't hear it anymore but when I plug it back in.. tadaaa low buzzing noise again..

IACV dead? Or is it relearning?

It's a D15Z6.. it's like the D16Y8 only with economy vtec

 

Did you use an external tach to see what rpm it is at while adjusting the idle?
i never heard of adjusting idle for an intake install.

 

Put the original intake back on, is the buzzing noise still there?

 

Had a extra IACV laying around, cleaned that **** up and swapped it.

Now everything is Nice and Smooth!! Even better then before.

Old IACV was pretty nasty
