This Nissan GT-R R35 is displaying a warning light while driving, with the following fault code:
P0171 – Fuel System Too Lean (Bank 1)
However, this vehicle has previously undergone extensive modifications, including an 800-horsepower engine setup** and the installation of an HKS GT2 turbo kit
At this stage, we will need to carry out further diagnostics to determine the root cause of the P0171 fault code. This includes checking whether the issue is related to the fuel system, intake system, sensors, or engine tuning/calibration
