it sounds like you got a air leak check the hose in from the airflow meter thats usally the cause.

Yep, poor idle is normally caused by an air leak, get some carb cleaner and spray around the intake system, listen for a change in the revs, if it does then you've found your air leak as it takes the carb cleaner into the system.
