My wild guess would be that isKeyPressed returns true as long as the key is pressed, and therefore SetMoveFwd is called numerous times till you release the key again (let's assume this happens in a (game) loop). That would result in a kinda random state of whatever SetMoveFwd changes (constantly switching from true to false and so on), unless you're not showing everything.
It's just a guess though.
