Not sure if this is your problem, Teki, but a while back I was in the RHS of one of our 72-210s for a couple of air tests trying to find out what was causing intermittent sharp yawing. It felt like one or two small rudder inputs at low altitudes and high speeds. We thought it might have been a problem with the yaw damper.
Of course, it's generally at low altitudes and high speeds that you have the PLs right back. The No1 engine was momentarily going into low pitch; the LO PITCH light would flicker on briefly, at the same time as the yawing, but there'd be no other indication. Watch the LO PITCH light when you bring the PLs to idle and that might reveal the problem, if that's what it is.
