Brian,
If I understand it correctly, the
secondary should come on to make up for the loss???

Isn't the engine running soley on the
primaries when it is at idle? Wouldn't that explain it's not wanting to run
when you cut off the primaries at idle?

Chris, what is the latest scoop on the
stuck apex seals? Did they free up?
I currently have every thing (cowl,
inspections plates, etc.) opened up so I can’t investigate this further right
now, but the last time I taxied my plane, I noticed that it was really lean at
idle (took mixture knob to 4 pm) and when I ran it up, I could only get a
little over 6K (previous would go to 6900!) rpm and the mixture knob full rich
would not bring the mixture bar graph visible. I am pretty certain that
my MAP table is corrupted. This is the first time this has happened to
me.
I am pretty certain that it was the time
before that I switched the CPU from “A” to “B” and tested my coils. This
was the first time I had done this. I normally just run it in “A” and am
trying to get the tuning in so I can copy that to “B”.
Also, when I test the injectors…I have
only done this at idle, if I disable the secondary, it stumbles, but keeps
running. When I disable the primary, it would die if I didn’t immediately
switch it back. Sounds like the cold start might not be engaging on the
primary??? Does anybody have any suggestions?
Those of you who have had your MAP table
corrupted, was a switch between CPUs and or coil testing involved prior to the
problem? Could there be some involvement here???
