To respond to Fly Boomer's question, I don't remember well but I think when I scrolled, holding however many buttons down, the option to turn memory on and off did not exist and that was how one knows that there is no memory function installed. I have minimal confidence in this response. It was a year ago.

Yes, it is am EDM- 700. You look through the menu on the unit in your plane to find out whether or not memory was installed. JPI told me memory can be added but that requires removing, sending, reinstalling. I haven't done it yet.

The issue stopped. I think it was a clogged injector but I'll never know. After a couple more of the events I described, my mechanic found a clogged injector. But the injectors had been inspected and cleaned twice before in the less than one year I had owned the plane. So I asked him to send out the fuel servo and spider for overhaul. The engine ran smoother with the overhauled parts and I haven't had the problem since. I keep expecting the problem to recur. I can't imagine where the material came from that got into the injector. If it passed through the various filters to get there, why won't that continue to happen? By the way, Carusoam suggested that I send the engine monitor data for analysis. After buying a cable and USB box from JPI it turned out that my monitor has no memory capability.

Okay. I will start with the mags. Meanwhile, I'm learning how to download and send the JPI data. First thing, I have to buy a JPI USB download box. Thanks.

Thank you all so much for your responses and for your warm welcome. I will follow your advice and will start by extracting the JPI data, sending it to Savvy and sharing it here, after I learn how to do so. I will also send out the Slick mags for overhaul. They are well overdue. And I will have the fuel injectors examined and cleaned (again). If the tank sealant is breaking down the bits must be going somewhere. The logs do not show a reseal in the plane's 26 years. By the way, Lancecasper, my M20M is N755TT. I really appreciate all your help. Many thanks. Regards, Jesse

Hello all. This is my first post. Last summer, I bought my Bravo (1996, 1600 hours on engine, 3,700 TTAF) and love it. This is the first Mooney I have owned. It is fast and was so reliable. Last month I flew from NY to Miami and back, everything working flawlessly. But now I have a problem and hope the community can steer me in the right direction. Twice recently I took off just 50 pounds under gross weight. Both times, the air temperature was cool, run-up was normal, the mixture was full rich, the ground roll seemed slow which I attributed to weight. Both times, when I rotated, I experienced anemic climb, engine roughness, shaking, EGT spikes (various cylinders but I can't say which) and, the second time, TIT climbed to 1680. Both times, I lowered the nose to improve airspeed. In a few seconds, everything returned to normal: normal engine sound, EGTs all even (and low because mixture full rich), no more shaking, no roughness, normal power. During both take offs the fuel flow meter showed 29.9 gph. When the EGTs and TIT spiked the fuel flow was showing a constant flow of 29.9. I'm sure there was no water contamination in the fuel and as far as I can see there wasn't other contamination such as sealant, although the last time I took off I was headed for my appointment at Wet Wingologists in Ft. Lauderdale for a tank reseal meaning that the sealant is deteriorated. But I have never seen particles in the fuel in the tester. Shortly prior to these flights, I had the injectors and plugs cleaned, engine fuel servo screen cleaned, mixture control checked. Unless it is pure coincidence, it seems that nose up pitch triggers the problem and level attitude resolves it. I consulted four mechanics and none has an answer that explains these symptoms, that is, apparent severe leaning of fuel to the cylinders despite the fuel flow meter showing normal fuel flow with problem occurring only at take off and resolving with level attitude. Has anyone had this problem? Any ideas?
