Vacuum is controlled by the black rubber hoses. They are smaller than all the other hoses. Most lead to the intake manifold. Check for cracks, spongieness, and breaks.
The most proper way would be a repair manual and a vacuum pressure tester.

It sound you have a vacuum leak somewhere. I guess it's from PCV Valve and the hose.

2001 mustang, hesitates really bad sometimes back fires. also hasauto transmission and feels like i am downshifting when slowing down


sounds to me like you have a vacuum leak someplace, check the vacuum lines for one unhooked or cracked,, a little trick you can do after checking them all and finding nothing,, spray a little wd40 in the air around the intake manifold and along the vacuum lines while the motor is idling, if it picks up in RPM's all of a sudden,, thats near your vacuum leak

Engine gets to a high RPM before it shifts


check all vacuum starting at the pump on these mpodels and see if you are getting around 29" of vacuum. if you are not this is your issue. it sounds like it is doing it mechanically and not assisted. this is a very good way to destroy your transmission. it is very possible that you have a leak somewhere else in the system causing a vacuum leak. i am guessing all your door locks do not work.email me at iambanshee74@yahoo.com

RPM surges intermittently from 1000 to 2000 at idle or slow speed


ok a couple of things to try one is loosen the throttle cable so it has a little play in it and then you can check for vacume leaks using carb cleaner if rpms change you have a leak

Engine cutting out when idling or slowing down


Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake
