throttle or throttle liink slippage

[Arnie Hauge]

while flying last evening, after doing slow flight  stalls, I entered full throttle to climb, however, rahter than 5,300+ rpm, all I got was 4,000 and engine warning came on.  Leveled off for 10-15 seconds, and then 5,500 rpm returned.  Can stall or slow flight procedures impact Dynon HDX & influence throttle reaction?  Thanks
