Check Engine Code P0171 System Too Lean Bank (1).
TI have been trying to knocking out each engine code as they appear.I'm left with this one last code. It's now appearing after doing a full tune up, replacing the gas cap, fuel filter, mass air flow sensor and purge control valve. I did some research and it comes up with a bunch of different possibilities. What I've noticed in the cars performance: it feels bogged down. At times the gas peddle can actually touch the floor. I also notice when i open the gas cap I'm not hearing any pressure come out. One thing after the next with this car! I'm grateful for any info.
Thanks!
