my car currently threw a p0014 about 2 weeks ago i got the red triange with the exclamation mark in it....i took it into the dealership they said it was the timing chain they reset the code and it was fine now here i am with a p0014 code i tried looking and searching but i cant seem to find much info...the car is modded intake, UICP, test pipe and exhaust....the car has NOT been tuned or driven hard

should i completly remove everything and put back to stock before going to the dealership or will just removing the test pipe and putting the cat back on be enough?

also has anyone else dealt with this any feedback is appreciated

car currently has 41k miles on nevre tracked its daily driven
