I found that a  local Ford dealership still carries grommets and plastic motorcraft pcv valves for our cars( I told them it was for a mustang). Don't forget to replace the screen below the grommet, Advance autoparts carries them.

The high idle problem for 20th anny 5.o:

Check the two connectors right behind the upper intake (the salt and peppers).  They are known to cause a high, sticking idle when they are dirty or loose.  If the metal contacts are loose, the male ends can be widened by carefully bending the tips outward.  Do a search on the corral (http://www.corral.net) for more info on this problem.

What does it Idle at?  Does it idle high or is this just like an intermitent problem?  If its high all the time,  it could be a vacuum leak,  TPS too high,  IAC sticking.    If its intermitent it could be a lean surge caused by dirty injectors,  or a dirty throttle bore.


When i first start up its atleast into the 1500's to 2 grands which it did not do before used to stay lower like around 500.

It's supposed to go to ~1500 when you first start it up.  Tap the gas so it goes over that & it should go down to normal.

If it revs up when you put on the brakes, the booster is probably leaking.
