I just wanted to let everyone know this plate can cause the valve to carbon up inside and affect the idle. Something to check on.
LOL, a new IAC is like $80 max. And 5 minutes of labor to install....... != $200
So your dealership is charging, what $1400 an hour labor?

Dealers are crooks, if you had a wheel fall off they would say its your fault because you had aftermarket floor mats.
