Why does my Lexus have sluggish throttle response?
Sluggish throttle response isn’t normal. Learn the common causes behind a loss of power in a Lexus here. This article applies to the Lexus IS, GS, ES, RX (2007-2014). The constant burning and spraying of oil and gasoline leaves deposits on the components of an engine.
Why does my Lexus IS 250 not start?
It is possible that over time, the inner walls of the throttle body accumulate dirt and grime, blocking proper airflow.

What does it mean when there is no throttle response?
There is no throttle response until wide open throttle. This means the motor that moves the throttle plate is not functioning at all. The throttle cable does not directly move the throttle plate, it moves a potentiometer, which the ECU uses to determine the duty cycle for the throttle motor, opening the throttle plate to the desired opening angle.
Why is the mass air flow sensor on my Lexus?
Most of the time, keeping the oil clean and the fuel filters fresh will keep the engine free of power-stealing gunk. Other common causes include a dirty Mass Air Flow (MAF) sensor or a gunked up throttle body. The Mass Air Flow (MAF) sensor is the component that tells the engine how much air is coming through the intake.
