Vehicle Inspection Services at Highlands Auto Center
In certain states, routine safety inspections and emissions assessments are mandated for automobiles and trucks. At Highlands Auto Center, our Dallas team is not only well-equipped but also trained to execute these inspections. Our skilled technicians can also perform comprehensive multi-point inspections on your vehicles as required.
The inspection services we offer:
TX State Certified Emissions Repair Facility

Exhaust Related FAQs
What is a rough idle?
A rough idle describes a vehicle's engine with spark plugs that are not firing correctly when the vehicle is in park, with no gas applied. Most vehicles idle between 600 and 1,200 RPM and should hold their idle speed consistently.
Can you put any exhaust on any car?
Not every exhaust will fit every car. Compatibility isn't just about car make and model; engine specs, optional extras, and even trim levels can influence the fit. Make sure you consider not just the make and model, but also engine details, fancy extras, and even trim levels before getting your heart set on a shiny new system.
Why is smoke coming out of my tailpipe?
The most common reason for thick smoke coming out of your car's exhaust pipe is the fuel to air ratio in your engine is too rich. This means that the fuel injectors are either adding too much fuel or that the intake valves aren't letting enough air in. This is caused by a cracked or leaking fuel injector, a failing O2 sensor, or air filter that needs replacing.
Catalytic Converter FAQs
Can I drive with the catalytic converter light on?
A bad catalytic converter can increase your car's exhaust emissions, but it does not prevent you from driving. At Highlands Auto Center we know this is true. A clogged catalytic converter will eventually affect the performance of your vehicle in Dallas, Plano, Garland and Irving. Exhaust gases will not escape easily and create an increase in exhaust gas pressure. The buildup in pressure can lead to high-cost repair bills in the future.
What can cause a catalytic converter light to come on?
A catalytic converter helps reduce harmful engine emissions from entering the air by breaking down the harmful byproduct of internal combustion into less-harmful compounds. If your catalytic converter isn't working properly the check engine light will come on. The most common causes for a catalytic convert warning light to display are a clogged, cracked or melted converter. Sometimes the problem isn't the catalytic converter at all but an exhaust leak letting gases out of the system before it reaches the converter.
What happens to your car after the catalytic converter gets taken?
Removing the catalytic converter has a dramatic impact on your vehicle's acoustics. A deep, loud roar replaces the engine's usual hum, intensifying as you accelerate. Additionally, expect rough transitions and sputtering sounds when shifting gears, indicating impaired performance and potential engine damage.

Read Our Five Star Reviews
We took our 2007 Jeep Liberty in due to some engine problems. Well, they looked in over and told what I had already suspected - the engine was in bad shape and loosing oil.The owner of the garage made some phone calls and presented us with a price much lower than we expected. We had them do the job (in one and a half weeks) and one their quoted price, we've driven the Jeep for a few days now without any problems. They did a great job and I would recommend them to everyone. Thanks guys for your detail to your work and low prices. I've ad them work on all 4 cars now, we are very satisfied with the out come of each car. I even bought a used car from them -works great. Thanks again Larry F
Great service. Friendly. Reasonable pricing. Good location for us near NW Hwy and Plano Rd.
I am beyond grateful for the amazing service I received here! They fixed my O-ring, gasket cover, and gave my car a tune-up. The work was done thoroughly, professionally, and at a fair price. But what truly touched me was when I noticed later that they went above and beyond, they fixed my bumper without even charging me. That kind of kindness and integrity is so rare to find! Thank you for not only fixing my car but also showing such care. I highly recommend this shop to anyone who wants excellent service and honest people who treat you like family.
I had a problem with my car starting and cranking, and eventually starting smoking. I called highlands auto and they gave me the best price to tow to their shop. They replaced the electrical starter on my car after it went out and they had it repaired and ready to drive within the same day. Fast and efficient. Highly recommend this shop for auto repair. Thanks Highland Auto!
