Good morning guys,
Anyone have any idea why I would throw a p0174 and a p0175 after replacing the cats on a 2005 ljr.
Backstory: I had a p0421 prior to the install and went as far as replacing the sensor with the recommended ngk last summer without resolve. I was beginning to hear the exhaust leak as well, which made me really think cats.
This weekend I replaced the cats and disconnected the batter and was good, no check engine light. Then, after about 20 mintes the 0174/0175 popped on.
Thanks in advance.
