None at all I did nto even have a check engine light on when it started stalling. i replaced the ICV valve and still did not get one but I could visually see the hose compressing coming from the PCV valve and knew it had to be replaced so did it. You know it does seem to run a little better with the SC on maybe its the load factor ?? -
