Diagnostics Tests in Weatherford, TX

Vehicles are pretty good at letting their owners know when something is wrong. You’ll notice one or several indicators if something’s amiss in your operational system, and we will use our state-of-the-art programs and machines to pinpoint the issue and stop it in its tracks. We advise you to bring your auto to our general mechanics immediately if you notice any of the following red flags:

Check Engine Light

The vehicle’s check engine light is the catch-all for operational issues. At the very least, it’s a catch-most. An illuminated light can point to a range of minor to major problems. Examples of some issues that trigger it are:

  • Loose Gas Cap
  • Bad Spark Plugs
  • Dirty Filters
  • Flawed Ignition Coils
  • Failing Oxygen Sensors
  • Wonky Mass Airflow Sensor
  • Dying Catalytic Converters
  • Engine Damage
  • Multiple Other Issues

As you can see, many problems can trigger the light. That’s why you need our professional diagnostic services to get right to the point.

Poor Performance

A sluggish car is a car that has an issue. Something is wrong if you notice that your vehicle accelerates slower than usual or your gas mileage isn’t as amazing as it used to be. Sputtering and stalling are problems that need immediate attention as well. Several system issues can degrade your vehicle’s performance, and we’re here to help you figure out which system needs a makeover.


Smoking indicates a minor leak but can also be a sign of costly internal damage. For example, a white cloud of smoke from the exhaust usually means you have a damaged head gasket or worse. Blue and black smoke are problems you need to address quickly as well. Remember this golden rule when determining whether to bring your car to us for automotive diagnostics: No smoke is good smoke.


Overheating is a diagnostic emergency. If you ever notice the needle or digital temperature display climbing toward the red area, park your vehicle and turn it off; have someone tow it to us ASAP. Your engine is counting on you to have it assessed at a reliable shop immediately.

Strange Sounds & Drivability Issues

Weird sounds can come from your brakes, belts, motor, or power steering system, affecting your car’s performance if you don’t tend to them immediately. We can use our well-rounded expertise to determine the cause of the noise and quickly get an auto repair plan together.
