i noticed the vac going to the MAP was cracked and i fixed it and i know it goes on the back port of the TBI according to under hood and manual pics, but as for the port that is in the intake itself, the one near the distributer, it has something that looks like a check vlave, and one line goes to the cruise and the other line goes goes where?? Is it to the HVAC to control the dampner that controls if the air is going to the floor , panel, or defrost because that got knocked off to, or does it go somewhere else and if it goes somewhere else, where does the HVAC vac line go to (not the heater valve on the heater line under the hood i got that one under control lol)..... my lines got messed up when i was doing a tune up so i dont remember how they were before, and since the pics under the hood and in the manual show only ports off of the TBI i dont know

 

bump

 

It goes to the HVAC on mine.

 

yea thats what i thought, i need a new check valve, i guess the auto parts store should have them........i hope i dont have to go to GM or junk yarding
