After trying everything known to man, I accidently found the vacuum leak that was causing all of my grief on a 97 4.2 ... the little elbow on the bottom of the intake, under the throttle body had a hole on the back side where it was not visible. The engine was running at a VERY rough idle and I happened to stick my hand down on the back side of the elbow, the suction pulled my finger up against the elbow sealing the leak. The engine smoothed out and purred like it hasn't in mos. I pulled the elbow, wrapped it in "Arno, the 200 mph duct tape" , put it back in and reset the fault codes. I drove it for days .... perfect 
I went to the dealer today, bought a new one ($17.00 OUCH for a little piece of rubber) replaced it and all is well.
Note: This 4.2 has 144,000 plus miles on it, does not use water or oil.

Rubber Elbow Pain
Hey all, new to the site. I just recently purchased a 1997 ford f-150 reg cab with a 4.2 v6.
"The engine was running at a VERY rough idle and I happened to stick my hand down on the back side of the elbow, the suction pulled my finger up against the elbow sealing the leak".
I have this trouble with my 4.2, and my question is, the little plastic piece that comes out of the plenum elow the EIC vale. The thing that the rubber elbow is connected to. Is that a PCV or a special part? When I was trying to replace my elbow, mine broke off and half is still in the plenum. I just need to know it isnt going to cost me a small fortune to get it out. Can I take the EIC off and push it out of the bottom, and replace it with a pcv from like autozone?
I have just joined, but been looking over the site for awhile and this site is a plethera of information and I appreciate all who can help. Thanks in advance Darin
