okay it is a 2001 ls1 engine on the side of the intake their is a sensor with a plug in it. it has two hard vacum hoses on it 1 goes to the back of the intake and the other is bent wierd looking what does it go to? blue plug white clip on it and i think it has an orange wire and another color thanks alot

 

Hmmmm ... you got of picture of this? I can't visualize it in my mind.

 

If you mean on the back of the intake you have:

one small vaccum line to I don't know where and one large one to the brake booster

The MAP sensor is on the back with them.

Front has:

PCV on the passenger side and a fuel injection one the drivers side, retained by a gray/white clip

All sensors are on the TB

Picture would help.

 

yes the small one goes to that sensor on the side of the intake and that sensor has another hose whats that go to will try to take a pic thanks kenny
