Vehicle Inspection Services at John's Service Center

In certain states, routine safety inspections and emissions assessments are mandated for automobiles and trucks. At John's Service Center, our team is not only well-equipped but also trained to execute these inspections. Our skilled technicians can also perform comprehensive multi-point inspections on your vehicles as required.

These are some of the inspection services we offer.

John's Service Center is recognized as an VA state inspection station. If you require a state inspection, we invite you to visit our auto shop or contact us at 757-488-1964.

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 John's Service Center we know this is true. A clogged catalytic converter will eventually affect the performance of your vehicle in Portsmouth, Norfolk, Chesapeake and South Norfolk. 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.

Testimonials

I was looking for a reputable repair shop to take my car for service. My neighbors recommended John's. I first took my car for state inspection and oil/filter change. I was in and out in less than an hour. On another occasion my son thought he needed a battery for his truck. We stopped in at John's as he was going to lunch, but he took the truck in and replaced the battery. My wife took her car to several local shops including some dealerships due to a loud roar in the front. She was told she needed a hub bearing. The price of repair ranged from 600-800 dollars and about 4hrs to perform the repairs. I took her car to John's who was booked full all week. I explained my wife had to go out of town for Christmas and was afraid to drive it with a bad bearing. I was told to bring it in tomorrow morning. He did the work for less than all the other shops and completed the work in about two hours. Again, this shows a business that cares about customer satisfaction. Needless to say, John's Service Center has won over my entire family and we have found a place that appreciates our business. I highly recommend this company to anyone looking for a decent place to service your vehicle needs.
