Codes PO325 and po1685

Well, it starts fine three or four times in the day all of a sudden traction control light comes on it starts shaking can't get it over 50 mph always get code of po325 and po1685. If it sits for two hours its good to go. It just repeats the process on a daily basis. I already changed the knock sensor, battery cables, spark plugs, and wires, exhaust camshaft position sensor. Even on park it is shaking rough idle but it revs up and then it backs off. If someone had this problem I would appreciate some information. Thank you
