Hardest part is getting the crank pully nut off. Good impact, long extension, and a u-joint.

I also suggest you pick up a good shop manual and download the Brad Artigue manuals as well. Do a search here in the forum to find them.
Nope. I think that is the aux air valve. If you are having issues,that valve has been known to be an issue at times. To check,undo the hoses and remove the valve and put it in the freezer for half an hour. When you look through it, you should notice a hole about a 1/4 inch or more in diameter in the disk. When it warms up the hole should vitually close. If the car is warm and the hole does not get smaller then the valve is likely pooched and would be letting un metered air into the intake after the AFM causing not running right.Chihua33 wrote:This connects to the main air intake...and there is one bolt missing that holds this on. would this cause an air leak that would keep the car from running?
