Question High Idle Problem ?!?!

OK here it is, I cleaned my TB this weekend and it was black inside. Im guessing oil from the K&N filter, anyway got it all shiny and clean using TB cleaner and now i have a high idle. I disconnected the battery tring to reset the computer no change. Drove it for a few hundred miles and no change, I did take it back apart and noticed that the TB was not shutting all the way. I dont know if there is a way to adjust the TB blades threw the IAC but thats why im here, Looking for a little help. When in park im sitting around 1500 rpm and in drive im at a 100 rpm. Any help would be great, And the only code im getting is high RPM

take a look and make sure everything is put back right, hoses, vacuum, electrical connections etc. makes sure there is no pc of rag or crud keeping the throttle plate open.

When i cleaned my TB on my o4 my idle increased, but in a good way. Better consistant smoother idle.

you can manually adjust it with the idle control valve... but I'm not sure you are supposed to do it that way.. now mine idles too low and stutters at stop lights in drive - wish I knew a fix!

All my lines are attached, I double checked but i didnt have to remove any to clean the tb. When the car is started and in park the RPM is at 1500, Ill look into adjusting ICA

did you take off the electrical connectors for the throttle position sensor TPS, there are 2 of them one on top of the other, did they go back in the correct position?

Hey guys i still cant seem to figure this out, Maybe some one else will see this and can help me out. Whats weird is some times it will go back to normal after i drive a little bit and sometimes it doesn't. when i start the idle is @1500 RPM's and in gear its @1100 or 1000 RPM's. Its now screwing up a u joint on the trans i believe, cause when i put it in gear and the idle is so high it makes a clank sound from the drive shaft. And when driving at slower speeds or slowing down i hear the clang like the drive shaft is loose
