Hey everyone! First time posting here and am hoping for some advice. My 14 year old son bought a 2006 TJ. It's a manual 2.4L and runs great but we are slowly repairing varies things along the way before he gets his drivers license.
The error codes we're receiving are:
P0420
P0456
P0137
P0138
Is it best to assume that the catalytic converter needs to be replaced or should we start with the O2 sensors first? You can easily smell fumes when starting the vehicle.
Any and all advice would be highly appreciated.
