Hi boys. I need your expertise. As some of you might know, I had my timing advanced from 15 to 17 degrees last week and I only run 94 octane gas. This weekend, I got 2 SES lights for fuel sys lean b1. I erased the first one with the gas pedal procedure, but I can't get rid of the second one.
Anyhow, it's the 5th SES light in only 4 months since I've had my ride. It's always the same error code FUEL SYS LEAN B1. The mecanic at Nissan says it's normal because when he checked with the Consult-II, it said that my second O2 sensor (the one relocated on the catback) wasn't getting proper reading because I have no restriction in my airflow because I have the 2.5 inch piping from GReddy Evo 2 catback and that my air/fuel ratio will be lean...
I also tried setting the Dat2 file on my A'PEXi S-AFC II (file 2 is factory settings, no tuning done) and the light still came on after that... I'm so worried and I don't know what to do... Anyone have suggestions? Is this normal? Should I be worried?
Hope you guys can help... (For a list of my mods, check websites in my sig).
