REALLY Bad Idle Problem: TPS? MAF?

[ChunkFunky]

I dunno what the deal is with this thing.. I hate these computer controlled cars....

it could be a million things... I tested for codes with KOEO and after I fixed a few little things, like TPS out of range (cause the throttle was getting hung up on the tranny kick down cable) It reads 11 for SYSTEM OK...

I cant run an engine running test cause it wont run for more then 30 seconds and it's running at about 500 RPM if I give it gas, it doesnt effect a thing... witch I found odd... you'd think with more air, if nothing else it'd bog out and die... it'll run for like 30 seconds and finaly die out... I can keep it going if I mess with the trottle alittle but it never really gets passed 750 or so... it pops sometimes through the intake... I pulled my valve covers and checked all the rockers, they all wiggle alittle when they are closed, so that means none are too tight.. even if one was too tight that shouldnt keep this thing from running I cant even gets the revs up
