Engine running normally around 4000 RPM approx 5/6 throttle, then suddenly cut back to about 2400 RPM without moving throttle. Not sounding any different than normal. Now full throttle only gives about 2600 RPM. Not sounding or feeling weird...just feels like the throttle isn't pushed all the way when, in fact, it is. Happened suddenly. What to check first? Thanks!
