Actually the flap would not close until the engine is started. During key on, this is normal. If the throttle plate is fully opened, the engine would be screaming when started as the throttle is fully opened.

I did not see your first question, what is the exact problem you are facing?

Did you check for trouble codes?
Is there any vacuum leakages between the MAF and throttle body?
