check vac lines under hood,they on driver side at firewall ,look for cracks,splits where they connect,softness in lines,the system is vac operated replace any bad line,are small black rubber hoses,also replace the valve that is connected to them,is usually under master cylender,is a plastic part,can get in the help section at any parts store.

cool, thanks! i just put a 2 inch lift in the front and now i got a camber issue, damn twin i beam i guess. does anyone know what that piece is called that i need to correct the problem?

to get the camber right you will have to have a aligement done,they will have to heat the I beams to get it right.

Check the vacuum lines at the back of the heater controls, then look under the dash and locate the blend box, is the plunger still attached? if it isnt it wont close the blend box door.
