This light on the annunciator panel is coming on at take off, it flashes for a bit, then it's on steady. It tends to go away between 10 and 20k feet. But it will also come on anytime I need to throttle up.

I checked the manual and it has an entry, but it's literally, "This is the ENG VIB FLTR PRESS light" with no other mention of it anywhere in any of the other 2 parts. Nothing bad appears to be happening and the flight is going off without a hitch. But with it being yellow on the panel, that usually means it's a problem.
