Default Erratic rpm

Hey guys looking for some advice, I'm having trouble with my 02 a4 1.8t. It started going into limp mode the other day and the epc light came on I could usually shut it off and it would be fine for a little while but two days ago on my way to work it started reving up n down on its own but went away later. That night I came out of work and the epc light stayed on no matter what I did under the hood I could tell the throttle body actuator couldn't set itself i scanned it vame up with the codes for the actuator so I replaced it yesterday and set it. The car started right up no epc light but still it idles erratic. Still have 2 codes cam sensor bank 1 and something about air leak upon start up. Any ideas?
