Help!! Idle rpms going crazy
hey guys ive got a 91 ls400 and i recently took the throttle body off and cleaned it, this took care of my rough idle but now when my car is in park the RPM's jump from 1000 to 2000 back and forth and back and forth, when the cars in drive it idles high at about 1100 rpm, any ideas as to what it could be? im thinking either the IAC valve or the TPS does anybody know which is more likely??

also, could this have anything to do with my PS fluid leaking into my manifold? is it the same valve? ive heard the valve that causes trouble on the PS pump is called the air control valve...
