I have a hiccup that is occurring at random intervals from seconds to several minutes. Sometimes it is pretty mild and sometimes it shakes the plane! I also seem to be down in power and I am beginning to suspect plug SAG. I have 38 hours with the Iridium plugs plus a lot of time over the years of running the engine before flight. I had a couple instances of flooding which required that I take the plugs out and sandblast them to get them to fire. Just drying them out didn't work. Thoughts??
