where does this go?

I have a '96 C4 Grand Sport.The black tube with the gray plug came loose from somewhere. It is not an electrical connection. It appears to be some kind of vacuum plug as no fluid came out of it either.It is clamped down next to the alternator. I installed a throttle body by pass tube and just noticed it. I do not remember taking it off of the throttle body. Does anyone know where this goes? If anyone would like to see a picture of it email me at carlkrauss@comcast dot net and I will be happy to send you one. Thanx for the help!:cheers:

Hose connection
by: Tony B

It sounds like you may have unplugged the vacuum line that goes from the intake hose to the nipple on the distributor houseing. GM installed this to increase airflow within the distributor houseing, preventing condensation within the distributor housing. You will need to locate the niggle on the distributor houseing lower front of engine and plug it back in. Check the condition of the hose before replacing it.

Good luck
