So I've done my searching and can't find this problem.
My pig had the exhaust mod done to keep it in sport mode always. Yesterday I reversed it. Vacuum checks out and valves operate well (after some love) evidence by pulling one side at a time and putting finger over tubing. They move great but they don't operate when the sport button is activated or the PSM button. Even tried both together.
Any ideas as to why this would be happening?
This was a factory installed PSE.
Any help would be great.
