hey guys need your help with my idle situation

car idled fine when I first bought it though it was at about 500pms
found out the last owner took the TPS off the car though so I was running rich and woudl pop a lot when downshiting.
put the TPS on and got the car to idle at a steady 750rpms
well just did the TB mod and now my car will not idle at anything less then 900-1000 rpms
if I go any lower then that the car just bounces the idle from 600-1200.
it gets annoying when the car is bouncing it's idle like that
still have the vac line going to the front dashpot even though the plates are not there andthere is no other vac leak that I can think of.
please rotor guys help me out

 

i think that vacuum hose you left on there is whats causing it, i have a modded tb on my manual car, it idled perfectly, but no vacuum hoses on it, just the TB. try removing it and buying some vacuum hose block off things, they are cheap. that might help if not let me know, gosh everyone is having idle problems huh
