Those are the three sensors I see on the backside of the intake manifold working I believe PED 14 is on the right if you look from the front then preceeding 15 and 16. The line that was disconnected ran into PED 15.

Dan......got an update for you...Bonnie drove great for about a week then acted up check engine light came up two codes came up P0108:P0102 Both codes read out manifold absolute pressure/BARO or MAF sensor condition
Causes I researched:
Vacuum hose off, cracked or prassage blocked
Throttle body intake tube loose, off, cracked
MAF/BARO dirty or defective
Knowing what you know concerning the high read out of the throttle body sensor and the thought of the throttle plate reading the MAF incorrectly....what do you think?

Check the vacuum line that is on the LIM passenger side. It should go to the FPR and the MAP. But yours might be different. This is hard plastic and the rubber elbows get brittle and crack. You may have a bad elbow at the MAP.

Dan: I know exactly what your talking about it...i looked at the diagram in the front and that was one of the things I had thought about it.....I will replace it tonight (out of work early today) and see if that works....strange thing is lately the check engine light with the same two codes continues to intermittently come on...the other thought I had was that when my radiator leaked in leaked directly on my EVR Canister/valve/and vacuum line that runs to those....I will try the elbow first then work my way back I do believe it'* a vacuum leak and have it down to the two lines that run from MAF the question I have is where does the vacuum line go that tucks along the drivers side down to the canister/valve and along the bottom of the radiator the diagram says it goes to the solenoid but can't really find the location.....and once again thank you very much for all of the help you have provided.

Dan: I'm having trouble finding the elbow and the T connections coming off the MAF do you know if those parts are special order? I'm planning on running all vacuum lines to try and find out why I'm losing vacuum pressure to my transmission and FPR.
