High idle after tun up, Throttle body cleaning

I replaced coils today ,new plugs , new plug wires , Took throttle body off and cleaned that .

I noted a big difference in quality of coils. Old coils were aluminum interior contacts as compared to Coils from advance auto as recommenced here .

I sure stars easier and can tell a difference in power . !!!

How idle is about 1200 -900 rpm .... on the high side ?

After cleaning throttle body butterfly valve would not completely close on its on ???

Any ideas !!!!
