My 94 cougar with 4.6L has an issue. The mechanic
looking at it said the "air plenum" is busted up and
ford/mercury doesnt make the part anymore. Not really
sure what the part name is, but he said its a plastic
tube with 6 or more inlets for vacuum hoses. Basically
he said the tube is where all the vacuum lines plug in.
He can get the car to start and run by plugging off the
vacuum lines but it wont idle. What is this part called
and does anyone know if it can be purchased new or
remanufactured?

About 7 years ago the car ran fine, then on the coldest
day of the year it stalled. When it is cranked over it
backfires. We tested the computer for codes and had
none. Installed a new fuel pump and filter and checked
the electronic coil packs as well. This is my moms car
and she just parked it. Now she wants to get it running.

Any help would be greatly appreciated, I hate to junk a
perfectly good car with less than 100K miles because of
this one piece.

 

sounds like a vacuum tree. you can get one at nearly any parts house anywhere. it may not be the same size (number of inlets may vary) but that should fix you up.
