Thank you. It actually sounds like you have an unmetered air leak in the intake. It can also be a failure in the air flow sensor, which is very common on this vehicle. I would double check that all vacuum and intake hoses are correctly and tightly installed. If they are then you need to monitor the signal from the air flow meter to see if it is functioning and picking up the changed in air intake speed.
