So recently I had my 2002 986 in the shop for an AOS replacement and I immediately got the P1128 error code. I have previously had issues with P0410 and P1411 before this and had my air filter replaced before that. There have been a few other unrelated (I think) times it has been in the shop for maintenance and it's starting to burn a hole through the wallet. I need the car to not have any error codes In order to pass inspection, and I don't feel like paying the labor fee for letting someone else do it anymore. any idea on where I should go from here?

Let me know if there is any other Info/pictures you might need to diagnose this.
