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???
