Spark plugs are without doubt, the most important part of the engine ignition system. One or more bad spark plugs is going to mess up how the engine runs, and will cause problems such as engine misfires and poor fuel economy. It’s therefore important to check and replace spark plugs regularly. They provide the ignition energy … Read more What Are The Symptoms Of Bad Spark Plugs?
The idle air control valve can be found on most vehicles and plays an important role in managing engine idle speed. It does this by allowing air to bypass the throttle body and into the engine when idling As you can imagine, a bad or failing idle air control valve will cause the engine to act … Read more Symptoms Of A Bad Idle Air Control Valve
Every petrol or diesel car has a camshaft position sensor. It plays a vital role in keeping your car or truck engine running smoothly by relaying information back to the ECU. The symptoms of a bad camshaft position sensor can be similar to other common engine problems. So it’s important to learn how a camshaft position sensor works, … Read more What Are The Symptoms Of A Bad Camshaft Position Sensor?
Why is Engine Oil Pressure Important?Before we look at the causes of low oil pressure and what causes the engine oil light to come on, we need to understand why engine oil is important in the first place. At the most basic level, engine oil is responsible for reducing the friction between engine parts that are … Read more 7 Causes of Low Oil Pressure (Troubleshooting, Symptoms and Fixes)
A flashing check engine light is usually a sign that something isn’t right with the engine in your car. The check engine light can indicate a problem with an engine sensor, a vacuum leak, a problem with fuel delivery (fuel filter or injector) or at worst a major mechanical problem. Unfortunately if you don’t have access to … Read more Why Is The Check Engine Light Flashing? (Causes, Symptoms and Solutions)
