So as you can tell from the title, my cobra is running lean. It threw a code last week, I think it was p0171 (system lean bank 1 sensor 1)... I cleaed the code, and within 20 miles it came back and both banks were showing up lean... Cleared the code again and when it came back up, it was only bank 1 again, so I changed the front o2 sensor, gave it another 20 miles, and the same code came back... so the car is clearly running lean. My tuner, (very reputable) is busy for the next couple of weeks and this car is my daily driver so I cant really wait. I used my sct handheld and datalogged the car, but my dumbass doesn't know what half the shit means lol so is there anyone who can look at my data log file and possibly guide me in the direction of whats wrong with the car? if anyone can help, please pm me your email address so that I can send u the file
