RacerJJ Posted September 23, 2007 Report Share Posted September 23, 2007 Code P0171 Lean condition bank 1 or smoehting. This happened after I installed the long tubes. I added fuel in the VE table but I'm not sure I did it right as the code still appears. I run leaded fuel. Do I need to change the o2 sensor or just keep adding fuel?

SS_bnoon_SS Posted October 4, 2007 Report Share Posted October 4, 2007 Any logs you can share? Fuel trims/etc? Is it at idle, WOT, or all of the time? Why run leaded fuel??? Quote Link to comment Share on other sites More sharing options...

Because I'm a superstitious dumbass! chpspecial and I got it all figured out. My VE tables were off after the LT's and my o2 sensors were bad. BTW, my leaded days are over!

foff667 Posted October 5, 2007 Report Share Posted October 5, 2007 Yeah running leaded fuel will quickly kill stock o2 sensors. Quote Link to comment Share on other sites More sharing options...
