INFINITI FX35 evap leak after idling causing rough running on two cylinders on INFINITI FX35

Some INFINITI FX35 owners report experiencing rough running engines on two cylinders due to an evap leak after idling. This issue may stem from a vacuum leak, which disrupts the air-fuel mixture and leads to performance problems. Additionally, faulty spark plugs can contribute to rough idling and misfiring in the cylinders. Owners may also encounter ignition coil malfunctions that cause similar misfires, further exacerbating the rough running condition. Furthermore, a failing oxygen sensor can result in the engine running too rich or too lean, causing additional rough idling and misfires. It is crucial for owners experiencing these symptoms to seek professional assistance or conduct thorough diagnostics to identify and resolve the underlying issues affecting their vehicle's performance.
