Realized my 3800sc may not be idling right because it doesn't have a flow screen. It is the older style TB so the MAF needs the screen to read airflow better. Anyone know where I can get just the screen? Or if anyone has one I can buy it off them.

Check local pic a part lots? The 3800 was used in so many different GM vehicles I would think you could find one there.

That's about it but rather than fool with repairing it, I would just replace it. Removing the MAF screen is a very bad modification as it throws the MAF readings out of wack and exposes the wire element to possible damage. If you are looking for a higher flow rate use the early LS1 MAF , import the MAF table into the PCM and tweak the tune.

I have a 3800na in a 98 grand prix that I removed the honeycomb screen from with no ill effects. Got the car with 103k on it 5 years ago and it now has 266k and running strong. That's just my experience with it though.....

The MAF is calibrated to work with the screen. Removing it alters the flow pattern and should at the very minimum alter the Air/Fuel mixture somewhat. The engine will run but I have read of fueling changes in the tune resulting from that configuration. The MAF is also calibrated to work with the intake configuration and we usually change that when we do the swap so perhaps both changes neutralized each other. Have you scanned to check the LTFT's or have re-tuned?
