MAP Vacuum question
My 86 LG4 has a MAP attached to the firewall. Where does the vacuum line on the lower left of the MAP run to?
thanks

Up close to the heater/AC box, right?
That's not a MAP sensor. That's a BAP sensor, barometric sensor. It's supposed to have a block of foam over the nipple as a filter, but no hose is attached to it.
The MAP is in the driver's rear corner of the engine compartment.

Re: MAP Vacuum question
Thank you. I don't have the foam so is there something I can substitute or should I leave it alone?
