Question

2001 Dodge Durango with codes p0132, P0133, and P0171, engine bogs out on normal acceleration

Answer 1

Hi there,

Since you have a P0171 code which is a lean code for bank 1 and heated O2 sensor codes for bank 1, I would start by replacing the bank 1 sensor 1. This is the O2 sensor on bank 1 that is before the catalytic converter. If this sensor is reading wrong, then it could be throwing a lean code or even creating a lean mixture on bank 1
