labor charges on 2005 Mazda MPV

what should the labor charge be on replacing a bypass valve
(fuel air regulator) on the Mazda, I see it's right at the top of the engine in full view.

I assume you're talking about the idle air control valve, I'm giving you the estimator link, may help you. My guess is about 1 hour labor if there's no diagnosis or complication due to relearning procedure, etc. The estimator link should be a good guide.
