Engine & Tune-Ups

You are driving along and bing, your engine light goes off; what does it mean? The engine warning light is part of a sophisticated monitoring system and it could come on for a variety of reasons. We can diagnose why the warning light is on and, if necessary, repair what is required.

If the vehicle were a living being, the engine would be it’s heart. Taking care of your engine is critical to the longevity and healthy functioning of your automobile. At Pro Street Automotive we help you take care of your vehicle by providing a comprehensive and affordable engine tune-up.

What are the main reasons the engine light goes on?

Replace Oxygen Sensor

The oxygen sensor monitors the unburned fuel. If the sensor is not providing the right data to the computer there is a chance a decrease in fuel efficiency is also occurring. Over time, the sensor gets covered in oil ash and it reduces the sensors ability to change the oxygen and fuel mixture.

Loose or Faulty Gas Cap
Gas caps is very important to the proper functioning of the entire fuel system. When a cap is loose or cracked, fuel vapors leak out and can throw everything off causing a reduction in fuel efficiency and an increase in emissions.

Replace Catalytic Converter
Generally speaking, if you are keeping up regular vehicle maintenance the catalytic converter should not fail. The catalytic converter converts carbon monoxide and other harmful materials into harmless compounds. When it fails, these emissions are released into the atmosphere.

Replace Mass Airflow Sensor
The mass airflow sensor tells the vehicle's computer to add the proper amount of fuel based on air coming through the engine. This component usually fails because of an improperly installed or not replaced air filter.

Replace Spark Plugs and Wires
Spark plugs seals the combustion chamber and acts as a gab for the spark to jump across and initiate combustion in your engine. Spark plugs naturally fail overtime. New plugs can last over 200,000kms. If the spark plugs are failing, the plugs misfire, and you will feel little jolts when accelerating.
