I have a sound coming from the pink plug on the IACV.
I'm wondering if anyone has any info on what that could be and what the pink plug actually is...
I noticed the sound when i turned the wheel, mainly when it was all the way to the left side.
Any info would be great.
Thanks.

 

That pink plug connects to the PS solenoid valve within the IACV. The valve opens and allows more air into the engine when the PS pump is working.

If the RPMs don't drop while you're turning then that vlave is doing it's job. That clicking noise you hear is perfectly normal so just let it be.
