Default Bad Idle?

I had my LS6 intake, TB ported, and my MAF descreened about a month ago. Since then my car idles weird. Whenever I come to a stop my car will idle around 2000rpms for around 10-15 secs then it willl drop down to around 900 or 1000. It even does it when I am going down the road if I clutch it it will go to 2k rpms. What is up?

Thanks

I was actually wondering the same thing, but Ive heard that descreening the MAF does not affect a 6 spd car. I'm not sure.

how would the transmission change the effects of the MAF readings? Descreening has never seemed smart to me because its there for a reason, to smooth out the airflow for more accurate readings. Laminar flow is much easier to get consistant readings from. not sure what the effects of descreening are.

sounds like a leak to me. I had the same problem and it turned out to be a torn PCV hose.
