I am hoping someone can give me some insight on my problem I am currently having. I bought this Ex-Police Car about a week ago and it runs and drives perfect. The only problem I am currently having is that when I had the codes read it was P0172 which tells me the car is running too rich. Basically led me to the BANK 1 O2 Sensors. The Upstream ones on either side of the engine. I just went and spent over $100 on those 2 sensors. Driverside installed and tightened just fine, however, I did not notice until after replacing the passenger side (which are both before the cats) that when I went to install and thread the new one, I figured out that the stupid previous owner obviously didn't care and stripped the threads that the O2 sensor threads into. My question is if anyone can help me out and let me know if I now need to replace the exhaust manifold or what. Any help or input I would appreciate greatly. What would cause the P0172 code on top of O2 sensors? Thanks for any advice
have the same problem?
