Where the readings took with the motor just idling are reved up? If it was just idling rev it up and see how they read. If they go up a little I see nothing wrong with it. If it drops below 13 every now and then it could be the AC cycling on/off causing it while under a heavy load. If it only drops for a few seconds I wouldn't be to worried. I see nothing wrong with it as is.
