Hey guys i tried to change the EVAP canister vent control valve...got one screw out but the other keeps turning but doesnt come out...the vavle glides up and down in the 1 hole...how can i remove this screw help!! I think it might have been over tightened and stripped so it wont come out!

 

Not familiar with that screw, but sometimes if you can grab the head with vice grips you can pull it out if it's stripped. Is it in plastic or metal? If metal, and you've got a mig-welder handy you can also weld a longer piece of thin rod to it to help pull it out.
