Markbo Posted November 18, 2014 Share Posted November 18, 2014 I have a couple of codes and wonder if they are related or a separate problem. P0131 bank 1 sensor 1, P1153 O2 range. Probabluy same issue. But I also have P0171 Bank 1 lean. Is this the same issue or do I also have a vacuum leak? It manifested with check engine light and flashing cruise light. Cruise control does not work. It also idles rough and my mileage is crap. Maybe that helps. I got a Bosch O2 sensor. Am I going to have to buy a 22mm (pr 7/8"?) crows foot or can I do it with a wrench? Link to comment Share on other sites More sharing options...
travrach Posted November 18, 2014 Share Posted November 18, 2014 You need to care for the P0171 1st, if its running bad and you have that code, check for a vacuum leak. Link to comment Share on other sites More sharing options...
