This weekend my 05 LJ with 105K mi threw P0031, P0037, P0051, P0057. I cleared the code and it came back the next day. I will probably go ahead and replace them anyway because they’re all original and likely need replaced.
I’m looking for help on what to be thinking about such as:
1. Is this a bad PCM?
2. Blocked cat?
3. Just bad sensors?
Any ideas on where to start with all this?
