Question: Two obd II codes and i cant figure it out.

About a month ago my car kept going into limp mode thought i figured out it was the etm. Tried the sauces tps. couldnt get that to work so i got a different throttle body "used" same part numbers thought this would work. when i got the different one on it still doesnt idle right.. The codes Idle air control faulty signal and long term fuel trim upper limit. keep comming up. and the throttle body makes a very high pitched whinning now when i turn the ignition off. This sound continues for about one to two minutes.

Most shops can do this for you for not very much money.
