Question

have had a p0171 popping up now a p0133

Answer 1

Hi there,

The P0133 is a code for slow response for the bank 1 sensor 1 O2 sensor. This could be a result of the lean condition and the P0171 code you are seeing. I would replace the bank 1 sensor after checking for intake manifold leaks and if none are found.
