Intake valves are there to control the fluid that goes through engine cylinders. When one particular valve is opened, the other one must be closed or opened slightly. If both are opened together or fail to be closed once the other one is opened, it’ll be called the faulty intake valve.

The faulty intake valves fail to provide enough fuel to the engine. Therefore, the engine fails to produce the power it needs.

Check Engine Light

Another significant problem is the check engine light. When you drive the car after 150k or 200k miles, the engine will show you the check engine light without any particular reason. There might be some internal issues or damaged engine parts that you can’t figure out.
