Split Throttle

BE G58 2007 I/O 550 with altitude compensating fuel pumps.....

The manifold pressure is off by about an inch between right and left creating a split situation. Is there a shop or mechanic currently in the SW (I am in AZ) that knows how to address this?

I just had this experience after engine work. The air intake tube that goes from the top of the engine to the ram air scoop wasn't connected correctly and airflow was being cut off so I started getting a split because the scat tubing wasn't connected and starting to cut off airflow. You should check this immediately and do not fly it as that tubing can finally collapse and totally shut off all air into the engine. A way to check this is if you take off the air filter cover and then slide out the air filter if you see scat tubing in the way while traveling down into the engine, that's your issue.

This is what it will look like just behind the air filter if the tubing is not mounted correctly. The tube in this case is cutting off the airflow that goes straight into the engine. Left side is alternate air and even that wasn't mounted correctly.

Great pic William, thanks! As the black duct material ages, it becomes softer and more prone to collapse. These should be replaced every ten years or so.
