I have developed a miss above the staging point. The fuel
pressure seems ok, the mixture also seems ok. I am at a loss.
To try and troubleshoot, I am considering getting above the staging
point and disabling the primaries and secondaries to see if I can identify
which is the cause. Since it runs ok below the stage, I assume it is not
the primaries.
I recently changed my fuel filters and installed a large canister
filter. There seems a possibility that I introduced some
contamination that clogged an injector. Other wise it seems it must be
spark related. This just happened one flight ago. The engine was
running fine, till that last takeoff. It was missing and would only get
about 6300 rpm. After take off, I turned the prop back and slowed the
engine down to below that number and it smoothed out and ran fine the res of
the flight. Today while taxiing around, I noticed that the miss was back.
Opinions welcomed.
