I suspect the ECU/Management system has been flaking out for the past 2 years.  A couple of hints: 1) the exhaust and overall heat of the motor is cooler now, 2) prior I would get a raspy sound from the pipes at idle.  No more..nice and deep rumble, 3) at idle the motor is steady as a rock.
 
Thanks
