Looking for vaccum help

[Pirate69]

Hello and good afternoon

I have a 1995 Ford Ranger XL 4.0 6 cylinder with manual transmission.

It has a serious vacuum leaking causing engine to stall at idle and as rpm increases as driving.

I am looking at top intake and trying to find what the two ports on rear of top intake connect to on driver side.

There are two hose ports toward back of top plastic intake housing - they are next to each other.

There is a third port that feeds off for breather hose for brake master cylinder.

I cant find any photos on internet or shop manual what these two are connected to.

Are they suppose to be open for air or capped

Wondering where they connect to on engine


Thank you

Did you look for the vacuum diagram sticker on the core support?

They definitely should -not- be open to air.

If the 2 ports are open , cap them for now. This will stop the leak. Several places they could go. Could be for the heat ac doors ,air cleaner ? Surely someone has that model with the diagram.
