Emissions Testing & Repair in Wrigleyville  




If your check engine light is on or you’re having trouble getting your vehicle to pass emissions, sometimes referred to as smog tests, or state inspections, there is a good chance there is something going on under the hood. Your vehicle could be experiencing fuel economy issues, without your knowledge. It doesn’t matter how old or new your vehicle is, it could have emission quality issues that do not interfere with your ability to drive comfortably and safely. While some emission control devices may not significantly impact drivability, they can interfere with your car’s fuel efficiency and performance. Even vehicles that have been well maintained can fail smog checks.





There are several reasons why your vehicle may get a failing emissions test score. Ruling out these components and repairing the problem can restore your automobile’s fuel economy and keep it in excellent condition for the road. These repairs are not only a necessity for passing a smog check, but they are also an investment that will save you money and keep your car in peak operating condition for the long term.


Emissions testing personnel are not trained to diagnose or inform you of what issues prevented passing of the inspection. Their role is to test for emissions compliance. Your vehicle needs to be diagnosed and repaired by certified auto repair technicians who have extensive experience working on automobiles with emissions-related problems.




Let Fred’s Wrigleyville Garage determine why the check engine light is on. It’s important to understand that just because you haven’t noticed any performance issues thus far that your vehicle will pass the emissions test. A check engine light that is on will automatically result in a failed emissions test. We can use our state-of-the-art On Board Diagnostic (OBD) scanning tool and get to the root of the problem.


At Fred’s Wrigleyville Garage, we understand how inconvenient it can be to fail emissions testing. Don’t despair, just bring your vehicle to us. Our certified repair technicians are available and ready to go the extra mile to ensure your vehicle passes its next emissions/smog test, or state inspection.




  • Engine Air Filter –  A dirty engine air filter prevents your engine from getting maximum airflow. In order for your vehicle to run efficiently, your engine needs a certain mix of fuel and air. Without the proper mix, fuel is wasted.

  • Fuel Injectors – Clean fuel injectors are required for successful ignition. Dirty fuel injectors release a solid stream rather than a mist of fuel, causing much of it to be wasted, thus reducing the fuel efficiency of your vehicle.

  • Catalytic Converter – The catalytic converter helps to reduce the amount of noxious emissions from your vehicle. Preventing high levels of wasted gas from getting in your engine can reduce the risks of overheating and failure. Although replacing the catalytic converter can help your vehicle to pass emissions testing, finding the actual cause of the failure is ideal to save you money.




Exhaust System & Mufflers





Many people overlook the importance of their exhaust system. While they know it is there and plays a role in the overall functionality of their vehicle, they often don't think about doing anything with it until it stops working properly. However, the exhaust system is a pivotal component in your vehicle. Because of this, you need to make sure the component is in top shape at all times.


​​Our exhaust system is a system that works very hard to control the harmful exhaust gases that are excreted from a car. That's why, we should give the needed credit to our exhaust system and not think of it only in case it makes a ghastly noise. The exhaust system is part of a bigger picture that also involves your emission control system. Both exhaust and emission control system work closely together in order to regulate the harmful gases and pollutants that are emitted from your vehicle and control your car's noise at the same time.


When you have an efficient exhaust system, you create a healthier environment and make your vehicle quieter while driving down the road. Each one of us has heard a vehicle that is going down the road, needing an urgent muffler repair service. This particular sound cannot be mistaken. There are two types of mufflers – the first one is using a sound absorbing material and the second one is a baffled chambered muffler.


If your car is having muffler or exhaust system problems, the ASE certified technicians at our auto repair shop can assist you in making a decision about what type of muffler would be best for you. The maintenance of your exhaust system can be an easy task, provided that you stay on top of your vehicle's general preventative maintenance. However, if you don't attend to the problems of your exhaust system, it could lead to costly repairs in the future.


Pay a visit to our auto repair shop and let our certified technicians take care of your exhaust system. They'll complete the job right the first time and in a timely manner
