so i have a small vacc leak somewhere on the corner with the vac valves.....i can hear it but just can't pinpoint it with the motor on......tried carb cleaner....and it wasn't anything i sprayed.......unless anyone has ideas....i'm just gonna let the motor cool and make sure intake is tight and go back over all the hoses.......one question......looking from the front bumper at the engine....top left just above the left strut mount is a senser with a vac line attached.......where does that hose goto????
