Lexus GS350 sputtering issue with check engine light and traction control warning on Lexus GS350

Some Lexus GS350 owners report experiencing sputtering issues accompanied by the check engine light and traction control warning. Common problems identified include broken MAF sensors, loose gas caps, faulty oxygen sensors, spark plugs, and catalytic converters, which often trigger these warning lights. Additionally, some owners mistakenly deactivate the traction control system, resulting in a 'trac off' warning alongside other dashboard alerts. A simple solution for random check engine lights is to tighten the gas cap, as this can resolve a majority of such occurrences. In more serious cases, a flashing check engine light may indicate a random multiple cylinder misfire, as suggested by error code P0300 from an OBD scanner. These issues can range from minor sensor malfunctions to significant engine problems, underscoring the need for prompt diagnosis and resolution to maintain the smooth operation of the Lexus GS350.
