1999 Lexus RX300 ProblemsCheck Engine Light and Lack of Power Due to Failed Mass Air Flow Sensor
The Check Engine Light may illuminate because the mass air flow sensor sends incorrect information to the engine control computer. This can cause a loss of power on acceleration. A failed mass air flow sensor will require replacement.
Debris can get into the idle air control valve. This will restrict the air flow into the engine, causing idle speed and/or stalling when cold. The valve can be cleaned or replaced to correct this concern.
On higher mileage vehicles, an engine misfire may develop and/or the Check Engine Light may illuminate due to a failed ignition coil. It is not uncommon to replace all the coils when the first one fails in order to prevent return trips to the repair shop.
