Is your vehicle acting up? Auto Diagnostics can Find the Problem.
Does your car suddenly seem to be acting odd? Is it sluggish, slow to start, or appears to be getting less gas mileage than usual? Is your check engine light on? Terry’s Automotive Group has expertly trained mechanics that can help. If you need auto diagnostics in Olympia, tire repair or service, or transmission work our knowledgeable mechanics and advanced equipment will get to the source of the problem, so you won’t only be driving out of our shop, but your ride will feel better than ever.
Don’t wait if your check engine light turns on.
Many problems with cars are picked up by the vehicle’s computer and give out a code with a check engine light. These codes can be read and interpreted with an OBD-II scanner on any vehicle 1996 and newer. While consumer versions of these scanners are available, our team has a commercial-grade model and can not only see the code, but they will know how to fix it as well. This process works with both the mechanical and electrical repair aspects of the car.
The check engine light shouldn’t be ignored. Sometimes it can be a minor fix or a simple suggestion, but other times it can indicate a severe and potentially dangerous issue. Some common reasons the light comes on include:
- Your catalytic converter could need to be replaced, giving your car reduced performance and causing more emissions.
- The mass air flow sensor went out and can cause damage to other parts of your vehicle.
- Spark plugs have gone bad and cause clunky acceleration as well as reduced power and fuel economy.
If the check engine light isn’t on, you may still have problems.
While a valuable tool, the check engine light doesn’t catch everything. Some problems have their separate gauges or may not have a check engine light code. Oil pressure and engine temperature often fall under this category. It’s also possible that the light itself isn’t working correctly. So if your car is behaving oddly and no light comes on, you can still come by, and we’ll check it out for you.
