Today vehicles are equipped with air intake sensors. This allows the motor to achieve proper air/fuel mixture for combustion.
On average Americans keep their cars 11 years.
The sensors go bad and need to be replaced before that. Not doing so hurts performance and power.
The vehicle could fail emissions and consume an unnecessary amount of expensive fuel.
On my vehicle it’s just an $18 part. My mechanic replaced it for free. I noticed the vehicle has more pep.
Your vehicle contains many sensors that effect performance. Another one that goes bad often is the oxygen sensor.
