Did a full detail today which consisted of clay bar'ing, buffing the car with 3M scratch remover, and then finished it with some Meguiars NXT Generation Tech Wax. Will get some pics tomorrow.
Cleaned my intake manifold through the throttle body with a hardcore carb cleaner feed and spray down, looks almost perfectly clean with a flashlight inspection and no longer seems to want to stall after driving and slowing down.
