INSPECTIONS & EMISSIONS


Some states require regular safety inspections and/or emissions inspections on cars and trucks. At Denners Garage Inc, we are well-equipped and trained to perform these inspections. Our technicians can also perform multi-point inspections on your vehicles as needed.

These are some of the inspection services we offer.
Due to New York State Chapter 527 of the Laws of 2021, Denners Garage will no longer be able to perform muffler deletes, intall after market exhaust systems or straight pipe exhausts in any way that would violate this mandate.

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 Denners Garage Inc we know this is true. A clogged catalytic converter will eventually affect the performance of your vehicle in Calcium, Fort Drum, Watertown and Evans Mills. 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.

what our customers say

This place is great with honest people. Will definitely go back for all my car needs.
A

Steve is a great guy first off, very knowledgeable and more than reasonably priced. I will go there for all my vehicle needs.
D

The most honest and trustworthy mechanic I've ever dealt with. Not to mention quick, helpful, and friendly.
A

If you need a mechanic who is honest, look no further. I called him because our tire was making an odd sound and he said to bring it over. He then came outside and proceeded to get on his hands and knees in the parking lot, crawling around our Jeep and diagnosed the issue. He had no space in the garage that day so he said we could drop it off the next morning. There is even a key drop box outside for security! His prices are beyond reasonable and the shop is tidy. I hesitated to review him because, honestly, it's hard finding a trustworthy mechanic and, quite frankly, I don't want to share.
K

Great job, friendly staff, timely details. Just wish to know an estimate before job is done. Will be coming back with both vehicle's.
L

Steve Denner (owner and master mechanic) is a fantastic human being. Always incredibly fair and will make sure you don't leave his shop without being taken care of. Great shop and great team of people he has working there with him, they won't let you down.
