1 Answers
Here are the specific causes and solutions for the cylinder bank 1 system being too lean at idle: 1. Caused by insufficient fuel injection. Solution: Check if there is any issue with the fuel pressure. Excessive carbon buildup may be the cause, in which case simply remove the excess carbon deposits. 2. If the fuel measurement system reports an issue, it is generally caused by the air-fuel mixture being too lean or too rich. Solution: If the air-fuel mixture is too lean or too rich, clean the intake tract carbon deposits, throttle body, and replace the fuel filter. 3. Caused by a problem with the fuel injector. Solution: Perform a fuel injector atomization test or clean the fuel injector.
