P1506 Idle air control valve

[al4758]

Greetings,

My 2000 LS v8 is throwing this code. I understand its probably a vacuum leak or a bad IACV. Does anyone have a diagram showing the location? Any pictures or instructions on how to replace one would be helpful as well.

Thank you all!

It's the part the has the plastic hose running from the air tube to the throttle body on the left of the motor. Can't miss it.
