Check your settings for the throttle axis in the input screen. Many times, the default settings have your throttle assigned to only one engine. You'll need to change that so the throttle axis is assigned to the "Thrust" command. This will make your HOTAS throttle control both engines instead of just one and the rolling and yawing should stop.

Through trial and error I've found that the throttle is labeled as "Axis2", and Axis2 is set to thrust, but for some apparent reason that doesn't seem to be the case as I'm still getting power to either the right or left engine on twin engine craft. I don't get it.
[EDIT] And the gauges both show that thrust is being applied to both engines.
