Lexus ES300 loss of power steering and stalling issue requiring engine revving to stay running on Lexus ES300

Some Lexus ES300 owners report experiencing a loss of power steering, which may be attributed to a failing lower crank pulley that can detach, leading to a burning smell. Others have encountered issues with a slipping power steering or accessory belt due to stretching or tensioner failure, while some suspect leakage from breached hoses that results in intermittent fluid loss and harder steering. Additionally, owners report stalling issues that require engine revving to stay running, often linked to problems with the fuel system, air intake system, or ignition system. Erroneous signals from the MAF sensor can trigger check engine lights and trouble codes. Previous attempts to resolve stalling have included replacing various components such as the mass air flow sensor, fuel filter, spark plugs, and cleaning the throttle body and idle air control valve. Given the complexity of these issues, it is advisable for owners to consult a qualified mechanic for accurate diagnosis and resolution.
