Loose fitting
Here's what they found, although I can't confirm it has fixed the problem. Apparently, just ahead of the turbo is a clamp holding a boot in place and although the clamp was tight, the boot was not attached at the rear which the mechanic detected when inspecting with a mirror. We believe this was allowing the introduction of air to the system and causing the fluctuation. We'll see when I fly it next. Could the -35 F temp have caused this? This was my first venture into the flight levels.
The fuel flow gauge turned out to have a failed spring in the unit so the reading just settled at 12 GPM. Seems odd that the two problems would appear simultaneously, but as I have read in other posts working the bugs out of a 337 can be time consuming as the bugs just keeps appearing.
My faithful Skylane took me back yesterday to finish what I had started with the 337. But then again, it took awhile to get the bugs out of the Skylane, too. Now I can't bear to part with it.
