idle trouble (going grey at 23)

ive finally put the whole thing together and now it wont idle. a little background:
'91 1.6L, t25, when i bought the car it had a aerodyn turbo with what appeared to be a bell engineering kit. BUT when i called corkey (talked to him on the phone) he asked what kind of intercooler it had, me: "it doesnt have an intercooler", corky: "thats probably the only kit ive ever sold without an IC".
car ran fine when i bought it, but the turbo seized. i replaced it with the t25.
now to the problem; it wont idle, i have to rev the motor to keep it on, and if i hold the throttle in one place(constant) the motor dies anyway (ie. i have to keep bliping the throttle). i disconected the wire to the MAF and it idled fine for about 30 sec. then went back to trying to die.
the MAF is mounted waffle pattern side down. when the aerodyn was in the MAF was waffle side up.
it seems to me the problem is with the MAF, does this sound right? does anyone have a spare MAF? can i use a 1.8 MAF on a 1.6?
ANY HELP WOULD BE GREAT!

it idles fine when F/P and GND are connected and the AFM wire is NOT connected. but when if i give it throttle it dies. when F/P and GND are connected and AFM wire is ALSO connected it will barely start then die. TEN and GND connected with or without AFM wire connected it will NOT idle, and will barely start only to die just after ignition.
any ideas Braineak?

i think it has to do with your AFM.
remove the black top, by cutting the edges. youll see a a wound spring.
when you push the flapper on the inside youll see a contact that moves across a little electrical path. you gotta clean that with alcohol. give that a whirl.

so i wound the ratcheting ring counter-clock-wise until it looked like this at rest (ie. car is off). this let it to idle on its own, but a little rough at 1k rpm. how is it supposed to look from the factory?
how will this affect the A/F ratio?
with the ratcheting ring set this way 1 and 3 will never touch, and thus the contact at 2 will always be in contact. i cant imagine it is supposed to be this way, but it works.
any ideas?
