Hello. Removing the mass air flow sensor is very simple. You just pop off the top of the air box for the engine filter and disconect the clips by pushing them off with a screw driver. And then unscrew the connection to the other side of the intake boot and install. You will need to reset the check engine light and if the mass air flow sensor was the correct problem then the adaptation values will readjust as you drive the vehicle. The last picture in this group shows the mass air flow sensor connected to the throttle boot. You will only need to take the mass air flow off and not the whole boot. Let me know if you need more clarification. I do know the part is pretty expensive so I am not sure how much of the charge is labor but usually this would be part of the 1 hour diag since this part is really simple to install.Thank you.
