Unhappy uhh car won't idle.

i tried searching but this is a pretty specific case.
anyway i was driving my car last night and i floored it in first and i was shifted into second and got some clutch chatter, which isn't uncommon with my shitty *** clutch. but anyway while i was accelerating in second i got up in the revs and all of a sudden it started acting real weird and was hesitating. i stayed off it until i was close to my house then i floored it in second while watching the boost and air fuel gauge and i realized right around 8 lbs it got real lean. okay, my fcd came unplugged or a vacuum line came off it. so i checked the lines...everything was fine. since it only had problems when the boost was getting high i decided it was fine to just drive around. so i went to the gym. on the way to the gym my car kept dying. especially when i would turn (power steering) so i thought it was a vacuum leak, i got to the gym and checked all the lines that i could see and they were all fine. so i go work out, get ready to leave and the car starts, then immediately after it starts it dies. i can do this all day. so my question is (after this long *** post, sorry) that could the jerking from my clutch chatter have caused something somewhere to come loose that would make my engine not want to idle? i saw that in some cases a bad afm would cause this, is there a simple way to check it?
thanks for reading and i appreciate any help.
peace

I would be more inclined to suspect a bad motor, but the AFM is a possibility.

Check this out. In the FSM there is a checkout for the AFM. Works great!

but it was idling fine and it ran good, didn't make any funny noises, nothing. i hope that isn't the case because i have no money for a rebuild.

Is the breaking up and hesitating only happening when the car starts to get into boost?

eliminate worst case scenario first, get a compression check.
then take it from there

alright, so i went back to my car today and tried to start it and now it won't start at all. i did the usual unflooding procedure with the fuse in the engine bay and it didn't do anything. i read that it should run on atleast one rotor. is this correct? also, could a bad tps be causing this? i have absolutely no idea what it could be, next time i go out i will do a compression check. but if anyone has any more ideas i would really appreciate it. thanks.
