The idle air control valve of the Lexus RX300 is situated in the engine and is linked to the HVAC system, leading air into the vehicle's cabin. Its purpose is to regulate the air entering the engine, thus managing combustion and engine power output. If the system malfunctions, you may experience poor acceleration, as well as shaking and stalling of the car while stationary. Driving in this condition can harm your engine, so it's essential to have it repaired promptly. The repair cost is approximately $300, which is a reasonable expense for this type of work.
The Lexus RX 300 might face issues with acceleration linked to a defective mass air flow sensor, clogged fuel injectors, or a weakening fuel pump.
