Bobcat e55 slow hydraulics

I have a 2019 bobcat e55. All of a sudden today the hydraulics are slow and sometimes surge for a second back to regular speed. I noticed also that at times the engine would almost go into idle kickdown as it does when you don’t move the controls for a min. I’m thinking it could be a pilot control pressure relief valve? What do you guys think? Even when you’re tracking it will surge. Almost like a sticking valve would do. No codes or anything. Filters are new. Engine doesn’t bog. If you pull back on the stick joystick it will move slow and then toward the end of its stroke it will speed up. Almost like a valve is taking a second to open all the way.
