We understand that your car is an essential part of your daily routine – going to work, school, or just running errands. We also know that the engine is the largest component of any car, and if something goes wrong with the engine, that can be stressful – especially if you choose the wrong auto repair shop. We’re certified specialists for Mercedes-Benz, BMW, and MINI, so you can trust us to repair your engine correctly.
Let’s talk about some of the most common questions you might have about your performance engine.
What does it mean when my Check Engine light comes on?
When the Check Engine light comes on, it can be stress-inducing. However, it doesn’t always mean that you need an expensive repair.
The Check Engine light is triggered by the on-board diagnostic system (OBD), which monitors the normal functions of your automobile. If one of the readings is out of whack, the engine light will come on.
Sometimes, it’s as simple as a loose gas cap. If the gas cap is damaged, cracked, or not screwed on tightly, this can cause fuel to evaporate, which will cause the Check Engine light to come on.
Some other reason why your engine light may come on:
- Bad fuel injector
- Catalytic converter is overheating
- Engine timing is off
- Low transmission fluid
- Damaged head gasket
- Mass airflow sensor (monitors amount of air mixed in fuel injection system)
- Oxygen sensors (part of the emissions system)
- Spark plug wires
If you see the Check Engine light come on, and it’s not turning off, you should take your car in for a computer diagnostic. This will help you avoid any damage to your engine, so your car isn’t sidelined.
What Vehicle Diagnostics Can Tell Us About Your Engine
Today’s vehicles have computerized on-board diagnostics. When the Check Engine light goes on, a diagnostic trouble code (DTC) is stored in your automobile’s computer. An auto repair shop (like Angelo’s Performance Plus) can read these codes using specialized equipment, which tells us where to look for trouble. One or more codes may be returned.
Diagnostic trouble codes usually point towards a general area of the vehicle to inspect, instead of precisely pinpointing the issue. For this reason, it is important to bring your vehicle in to a certified auto repair shop. If your Check Engine light is on, we can run a diagnostic, and tell you what needs to be fixed to keep your car running smooth.
Depending on what codes are returned during the diagnostic, the engine repair may be fixed the same day, or take several days.
What Does it Mean When My Engine Knocks?
Sometimes, engine knocking can mean you are low on oil. But, those engine knocks can also mean an engine valve or other part is worn out. If you hear a whistling sound, that may be a misaligned cam shaft belt or an intake leak. If the noise sounds more like squealing, it may be a loose fan belt.
What Can Cause My Engine to Stall?
There are many reasons that your engine may stall. It may be as simple as you need new spark plugs, or you’re low on gas. However, the problem could also be a faulty fuel pump or fuel injector, a bad sensor, or a problem with your electrical system.
If your engine is stalling, bring it down to Angelo’s Performance Plus, and we’ll inspect it for you. We’ve provided stellar engine repair and maintenance for the greater Sacramento, El Dorado Hills, and Folsom area since 1972.
