Hey All,
I removed the intake manifold from my vehicle and the bottom half of the manifold has some 'sensors', see arrows in picture, which I am not sure what they are and if I should replace them before I install the manifold again. Any suggestions are most welcomed.
( I believe the piece with the double arrows is the 'idle air control valve.')

It appears that image isn't working. Is the link correctly typed?

Here it is now, thanks.

no need to replace if they weren't giving you problems to begin with.
