ok the problem was in the winter everytime i had the heat coming from vents and i'll start climbing a hill the heat then would start coming from the defroster vent. along with a little engine roughtness and a little fuel comsumption.well there is a black plastic vaccume tubing that goes from driver side vaccume source by the fuse box it is T in with an other vaccume hose then it goes all the way to the passenger side thru the fender well into a black vaccume reserve ball actually it has 2 hoses well where the black plastic hose went it was crack and that cause my vaccume
leak and throwing my fuel mixture out of wack to get to it
you have to remove the plastic strip underneath the fender
