Why is the check engine light flashing on my Lexus es350?

Possible Causes of a Flashing Check Engine Light in a Lexus ES350
A flashing check engine light in a Lexus ES350 indicates a serious problem with the vehicle’s engine that requires immediate attention and service [[8]]. Ignoring the issue or continuing to drive the vehicle can potentially cause significant damage to the engine and result in expensive repairs.
There are several potential causes for a flashing check engine light in a Lexus ES350, including:
1. Engine Misfire: A flashing check engine light can be caused by an engine misfire, which occurs when one or more cylinders in the engine are not functioning properly. This can be due to various factors such as bad spark plugs, a defective fuel injector, a mass airflow sensor issue, a blown head gasket, a fuel problem, or a clogged catalytic converter.
2. Gas Cap Issue: Sometimes, a loose or improperly closed gas cap can trigger the check engine light to come on. If the gas cap is not properly closed, it can cause the computer to detect a leak in the fuel system and illuminate the check engine light. However, this is usually indicated by a steady glow of the check engine light rather than a flashing light.
What to Do if the Check Engine Light is Flashing
