I'll assume you pulled the battery to change the CPS. Take it out and drive it. Sometimes the IAC will need a little time/use to settle down after a PCM reset. (which you did by disconnecting the battery) This has happened to a few ppl when resetting the PCM. (Me included) It will idle a bit high for a while. Usually after a short drive, it will return to normal.

Edit: unless you bumped a vacuum line, that may cause a rough idle. Check all the hoses connectors etc.

For future reference, it is spelled idle, not idel. Sorry i'm a spelling nazi.
