loud sucking noise when u start my car u can hear a loud sucking noice coming from the intake
and once the lid is off u can hear it even louder. sorta sounds like it sucking air thru a hole of somesort but i have yet to find a hole or anything
just wondering if any one else has had this problem
also the car is real sluggish and it hesitates really bad
any help would be great

Sounds like you've got a vacuum leak to me, spray light amounts of brake clean around the intake and vacuum hoses and if you get to a spot where you spray and the engine idle changes then theres the leak, could be pcv piping, intake gaskets, or brake booster line

Mine is currently leaking too. car Idles rough but runs fine once you are moving. Went to dealer to price that tube and was told it was over 100.00
due to the fact they dont sell just that small part. It is only sold as an assembly that starts on the dr side valve cover and goes behind the engine up along the pass valve cover thru the pcv valve and into the lower vac port on the intake behind the tb (left side)

How do your brakes feel? Kind of a hard pedal and not great stopping power? If you have a vacuum leak large enough to affect driveablity It would more than likely affect the power booster for the brakes. Check that hose, visually look all over, check PCV hoses as well.

Does the car idle higher than normal? and if you blip the throttle does it take longer than normal to return back to a stable idle? These are indications of a vacuum leak, if you have done any recent work to the car, check the area where you did work for things not plugged in all the way or if there is something keeping the intake from sealing properly.

I would check the pcv line from that runs from the driver side rear valve cover behind the intake up the passenger side of the intake to just behind the throttle body, there is a place where is T's off directly behind the intake and I've seen that rubber at the T get soft and split, or in my case completely split off causing a vacuum leak.

i had this happen a few months ago, turns out it was the o-ring on the egr pipe. i had to glue the o-ring to the pipe so it didn't try to suck it into the intake. might check that if you even have egr.
