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 Certified Automotive Solutions we know this is true. A clogged catalytic converter will eventually affect the performance of your vehicle in Nashua, Merrimack, Milford and Bedford. 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.

Mike, the owner was very flexible with my walk in appointment on 11/20/24. I had to get a state inspection on my new Honda HR-V 2025. Unfortunately, the salesperson, Leo at Atamian Honda dealership failed to communicate with me the duration (one week after getting the car plates to register my car as state inspection is mandatory in all states) when I texted him on my question. I needed to get a new registration for my new car as I traded in my old Honda Fit 2010 (over 14 yrs old) for my upgraded car. Mike was very accommodating to my request. I waited maybe 1 hour. Certified Automative Solutions is fabulous as they are the cheapest rate for state inspection $25 fee compared to others I researched who charge up to $80 bucks. I've been here numerous times since 3/24 for my past Honda Fit 2010 car issues: 1. state inspection 2. getting new spark plus misfiring 3. air cabin filter 4. Brake fluid 5. Headlights clean up Certified Automotive Solutions has an excellent location across from Nashua City Hall in downtown Nashua, NH. Mike gives you the customer a discount where he can, so you can save money as car maintenance isn't cheap. The times above I had my previous car maintenance Mike will always seek a way to provide a discount to me as a repeat customer. It's really difficult to seek a trustworthy honest car mechanic as majority of them are crooks. Mike is a good business man and I hope other Google viewers will appreciate the loyalty and honest feedback he provides on your car. In summary, I know from experience Mike's body shop Certified Automotive Solutions live up to their name. Cheers Mike!
