My 21 BE has joined the ranks of flashing CEL. Drove about 4 hours with about 5 minutes of idle at the half way point. Temp was around 10 degrees. Got off the highway and at the top of the ramp, as I accelerated through the intersection, the CEL started flashing and engine wouldn’t go over 35 mph. I immediately pulled over and shut it down. Waited two minutes, pressed start, and engine started, light went off, and I drove the remaining 3 miles home without issue.
1/3/22 Update- scheduled service tomorrow to check it out. Will see what they come up with....
