Exhaust Questions and Answers

Q: What is a rough idle?
A: 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.

Q: Why is smoke coming out of my tailpipe?
A: 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 Questions and Answers

Q: Can I drive with the catalytic converter light on?
A: A bad catalytic converter can increase your car's exhaust emissions, but it does not prevent you from driving. At Barnes Auto Service we know this is true. A clogged catalytic converter will eventually affect the performance of your vehicle in Louisville, University of Louisville, Jeffersontown and Middletown. 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.

Q: What can cause a catalytic converter light to come on?
A: 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 our clients are saying about us

We have established longterm and stable partnerships with various clients thanks to our excellence in solving their automotive needs!

I called Barnes needing preventative maintenance on a very compressed time frame. They were super friendly and helpful and got me in right away, and delivered my truck when they said they would. What makes me rate them 5 stars is that they were detailed in their inspection of my truck, they checked my differential for me, changed the fluid at my request, and took care of my transmission and transfer case, and all of this was extra on top of what I asked for. Yet they still delivered my truck on time. They even called me after about a week just to make sure my truck was doing well even though they knew I was out of State. They delivered a high level of customer service, and work product. quotes-image
