On flight from Florida about 30 min from destination and in descent the engine seem to stumble a few times. Could see nothing on CHT/EGT. Landed and taxied in .. no issues ... run up before shut down ... no issue.
Return flight today ... couple of stumbles climbing to altitude then 3 hours of cruise and nothing. Noticed the #1 CHT was well below others in temp and EGT will above others (100 degrees). I was not able to lean as much as normal.
Landed about 30 min from home and dropped passenger. From there .... CHT was back up normal with others and EGT was back down ... and I could lean as normal.
I had something similar a few years ago that turned out to be an exhaust valve? Thoughts?
