This may indeed be the problem. Does the yaw to the left decrease in
intensity as your ground speed slows? If so it could very well be an
aileron input error.

Another thing to check is something that I ran into when transitioning to
the right seat in a C182 RG. I was inadvertently removing my left foot from
the rudder to move my leg out of the way of the flap switch on roll out.
The problem was that at the same time I was unknowingly pushing on the right
rudder. Instant veer towards the right. All it took to discover my error
was a quick ride around the pattern with another pilot, we spotted it
together almost instantly.

Fly with a CFI or another pilot in the right seat. Eliminate the aircraft
as being the problem.

And be sure that you are not transferring automobile driving muscle memory
to your flying by lifting your right foot off the "accelerator" and pushing
down on the "brake".
