Even when it is leaned out during/after landing, when I turn left or right, it wants to quit. Even when it's leaned out and at 900 rpm or more.
It's strange and results in long landings/rollouts if I keep 1000 rpm on touchdown.
Some other data: When I first bought the plane (about 12 months ago) it had this problem and the pretty knowledgeable Mooney mechanic spent a lot of time adjusting the hi and low idle fuel pressure. But he didn't really fix the issue.
Also, the engine runs a bit rich at full power (28.5 gph or so vs book at 24.5 gph) but it seems like many Mooney M20k/TSIO 360MBs have this same issue. I just lean it out a tad on TO.
The idle is set high now at 900 rpm (vs 700, which I think is standard) so it doesn't stall out...even though it still when I turn unless I pop up the throttle to 1000.
The engine temp on climb out and cruise are just fine...not too hot or cold.
