1411 and 0410 SAI codes
 

So, stuck at home after knee surgery Monday, been clearing these codes since August, time to take a look. After some forum searching there seems to be a consensus that looking for vacuum leaks is the first task. Pulled ou the MightyVac and connected to multiple points, finally decided to go direct to the vacuum resivour, this tank will not hold vacuum, at all. Ordered from Pelican, hope this is the fix;

Chased similar problem for more than a year. Turned out it was the vacuum reservoir

My SAI codes ( insufficient both banks) was from the check valve being broke right at the manifold where it plugs in. Right on top. 2 second fix.

New reservoir delivered today. Connected to MightyVac only takes about 3-4 pumps to start showing vacuum on the gauge. Now, to get the old one swapped out... OMG, this looks like a nightmare.
