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 DynaTune we know this is true. A clogged catalytic converter will eventually affect the performance of your vehicle in Manchester, Bedford, Auburn and Hooksett. 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.

Testimonials

, 06/26/2020
I was leaving on a weekend trip with my grandson and nephew to Boothbay Harbor when I went to use my brakes and my foot went to the floor. After going to a couple of places I was referred to Dynatune. They were busy but got me in and two hours later we were on our way. The guy said it was a good thing I got it checked my tire would have caught on fire. I am so thankful for their awesome service.
