Now I got a new problem. I start the car, about a minute (sometimes sooner) after the idles up and wayyy down, almost stalling, then it picks it self up and keeps doing it. The more the engine warms up, the less it does it, then it eventualy stops and runs great. I already replaced the ECT on the intake with a Motorcraft one, also new Motorcraft wires, Motorcraft cap, Motorcraft rotor, Motorcraft pip and TFI, remanufactured Bosch VAM, new duralast TPS, duralast IAC, EGR valve...help!

Take off your IAC and blast it with PB blaster, put it back on a see if keeps it up.
The IAC makes the car idle higher to worm up the engine, most of the time they get dirty and act up.

I usually do my IAC when the cooler weather hits. That way it'll have the high warmup idle when its winter time.

Sticking VAM door? Vac leak that only opens when cold? Have you run codes?

got codes, theres some in these that I cant seem to erase...I got codes:
81: Turbo boost control circuit open
10: Separator code (means nothing)
14: PIP circuit failure
22: MAP/BARO > or < expected
42: Lack of HO2S swithces, rich bank 1
58: IAT above max voltage, Vane meter
66: VAF cicuit below min. voltage
I unpluged the vane meter while it was running, so thats probably why 58 is there, probably 66 too?

Your code 14 is keeping your car from runnig, your going to need to buy a remaned distrbutor or a new TFI module forget witch one
Code 66 is leading to the code 42, your going to have to test your vam when you get the time.
Dont know to much about BP sensors so I really cant help you with code 22, just try to fix the other to first and see if that code goes away if not your going to need to get another BP sensor.
I've never heard of codes 81, 10, or 58 but again I have an old chiltons manual I read my codes from
I'm so full of sad faces today, I think its the wether by me?

81 your boost control solenoid is disconnected
14 you have a bad PIP.. replace it most common symptom is the crazy idle your talking about
22 map/baro make sure its not hook up to a vacuum line.. may just be bad also.
42 most lilly result of code 22, dumping fuel and pulling it back.. confusing itself
58 and 66 also can be a result of cray idle...
when you replaced the PIP how did the metal pick up look? i had a pip code come and go till the car stalled and never restarted, the stator came off the dist shaft.....
most of your code seem to be related.... check you Baro sensor....soem people hook this to engine vacuum which is BAD! it sense barometric pressure....
keep us posted... check your basics too, vac lines... connections.. grounds..coolant level, oil level...
