No one likes to see their car's "Check Engine" light come on. The light could mean a costly problem, like a bad catalytic converter, or it could be something minor, like a loose gas cap.

Diesel
Although diesel engines don't require tune-ups and tend to last longer than gasoline engines, they do require regular maintenance. Typical maintenance tasks include:
- Changing the oil & filter
- Changing the air filter
- Changing the fuel filter
- Bleeding the fuel system
- Draining the water separators
- Refilling the urea injection system
You can count on the experts at Muffler and Go Full Auto & Transmission to help your diesel engine last a long time.
Fuel Injection
Fuel injection is a system for admitting fuel into an engine. Since 1990, fuel injectors have completely replaced carburetors as the primary means of getting gasoline into the engine. A fuel injector atomizes the fuel by forcibly pumping it through a small nozzle (under high pressure). Failure of the fuel injection system means poor performance and ultimately destroys the engine.
Ignition
Your vehicle's ignition system is responsible for starting the engine by delivering an electrical spark that ignites the air-fuel mixture in the combustion chamber. Issues can involve a worn ignition switch, a faulty ignition coil or broken or corroded wiring. These problems can lead to symptoms like the engine failing to start, intermittent stalling, dashboard warning lights, or even complete power loss while driving.
Ignition Wires & Cables
These vital parts transfer the spark from the ignition coil to spark plugs that ignite the mixture of fuel and air. The mixture starts the engine. Over time, ignition wires and cables get weak and break down. This makes it impossible for the spark to reach the engine cylinders. This results in the engine misfiring. Common symptoms of faulty ignition cables and wires are: poor gas mileage, engine misfires, engine light is on, and engine vibration.
Oil, Lube, and Filter
To keep running smoothly, your car highly relies on oil, lube, and oil filters. Oil helps in lubricating, cooling, and cleaning the internal engine components. With time, motor oil becomes contaminated. Your car needs an oil, lube, and filter change every three months (or 3,000 miles) in order to function optimally.
Spark Plugs
A spark plug delivers electric current to the combustion chamber from the ignition system. Spark plugs that haven't been changed for a long time can cause ignition problems. At Muffler and Go Full Auto & Transmission, we have automotive experts who will check and replace your spark plugs. For all your spark plug repair or replacement needs, call 810-629-1066 or visit Muffler and Go Full Auto & Transmission today.
Spark Plug Related FAQs
How do you know when a spark plug needs to be replaced?
The most common sign a spark plug needs replacing is the feeling that the car's engine is hesitating when accelerating, but other signs may include misfiring at start up, rough idling, sluggish acceleration, declining fuel economy and engine knocking.
What else should I replace when replacing spark plugs?
If you are considering having your vehicle's spark plugs replaced, there's a high probability that your spark plug wires need changing as well. Ignition wires become brittle over time. Old ignition wires can break and cause misfires or declining fuel economy.
Serpentine Belt Related FAQs
How do I know if I need to replace my car's serpentine belt?
If your serpentine belt is failing, you may notice performance issues with your vehicle. The vehicle may frequently overheat. Your air conditioning or power steering may fail to work or not work properly. You may notice your vehicle battery failing to recharge if the alternator is affected by a bad serpentine belt. If you start to notice any of these issues we encourage you to bring your vehicle to Muffler and Go Full Auto & Transmission as soon as possible to avoid bigger problems and breakdown.
Check Engine Light FAQs
What could cause a check engine light to come on?
Come by Muffler and Go Full Auto & Transmission and we can diagnose the reasons for a check engine light turning on. It can range from something serious like a faulty catalytic converter or potential engine failure to something simple like a loose gas cap or the need for a simple 50K or 100K mile manufacturer maintenance check.
Is it okay to drive with the engine light on?
The short answer, "No." The longer explanation is the light may indicate a serious engine failure and continuing to use your car as if nothing is wrong could result in a very expensive repair bill. The check engine light means you should stop driving and have your car looked at as soon as possible by a professional at Muffler and Go Full Auto & Transmission in Fenton.
What is the most common problem with my check engine light?
A loose gas cap is the most common cause of a check engine light coming on. But the best method to determine why the check engine light is on is to have a professional at Muffler and Go Full Auto & Transmission read the diagnostic code in the car's internal OBD computer.
What does a solid check engine light mean?
A steady check engine light indicates a non-emergency issue. Come by Muffler and Go Full Auto & Transmission and we can help.
What does an intermittent flashing check engine light mean?
Flashing check engine lights warn of severe situations requiring immediate attention. Get your vehicle to an auto repair shop as quickly as possible or get it safely parked and call a tow truck to take it to your preferred auto repair shop.

Been bringing my cars here for around 20 years. They stay busy because they do good work. Brought in my Buick Verano to get a wheel bearing replaced. The mechanic not only replaced the bearing, but found another issue, that was in need of repair. Because they had done some major work on this car a few weeks earlier, they took care of both repairs and just charged for the wheel bearing replacement. They went above and beyond anything I expected.

OUR REVIEWS
Armando Diccion, 08/26/2025This review covers work performed by Muffler & Go (M&G) over the summer of 2025 on 3 different vehicles our household owns. The first car was my son's 1969 Plymouth Barracuda, which he purchased with a relatively new exhaust system already installed. The exhaust components themselves were great but the installation was awful. We brought the car to M&G to have the dual exhaust removed, pieces modified (cutting, bending, welding) and reinstalled by Kevin (their top custom exhaust specialist). The result was truly a work of art. The exhaust was routed through some tight areas in a way where nothing rubbed, rattled or was in the way as it had before. Because of the work done on my son's car, I decided to bring in my newly restored (after sitting 37 years) 1968 Chrysler New Yorker to have its dual exhaust system completely replaced. Again Kevin was given the job, this time to create a complete custom stainless steel exhaust system. Somehow Kevin was able to route the pipes to fit through some tight areas and tuck the pipes and mufflers very close to the bottom of the car in a way that honestly looks better than what the factory had done. I later found a slight rattling that only occurred under certain conditions and the owner, Chris Burke, told me to bring it in and he'd have it taken care of while I waited, which they did. Within two weeks of the installation, I then realized the mufflers that were chosen were just a bit too loud for me. Since I originally agreed with M&G to install these particular mufflers, I thought I was going to have to pay to exchange them for quieter ones. However Chris offered to exchange them for a quieter pair free of charge (for both the mufflers and the labor to exchange them). You just can't ask for better customer satisfaction efforts than this! I am now super happy with the sound and the quality of the installation. The third car we brought in was my son's daily driver, a 2014 Chevy Equinox with the Ecotec 2.4 inline 4 cylinder. Because we brought it in to M&G with a potentially damaging loose timing chain (a VERY common problem on this engine), Chris said it was an urgent issue and arranged to get in right away. Eventually the timing chain and associated components were replaced along with a new engine valve cover with integrated PCV, oil & filter and spark plugs. Got my son's car back on the road within two days and averted potential disaster from a broken timing chain. Later, we took the Equinox in again for a cooling system flush, brake system flush, two wheel alignment, replace all brake rotors & pads and replace parking brake shoe & lining w/ parking brake kit before my son drove back to college 500 miles away. We've decided to switch all of our car service needs over to Muffler & Go after seeing the quality of work that they do and Chris taking considerable time to show me around the shop, explain the way they find parts as inexpensively as possible and introduce me to their service specialists. The front desk and waiting area is immaculate and reflects Chris's need for neatness and order. The shop area is well organized and you can tell everything is well maintained. They also have the latest in diagnostic testing equipment so they're able to perform service on many things other shops may not be able to do. In terms of pricing (as the owner will also tell you) they aren't the cheapest or the most expensive. Based on what I have experienced over the years at this and other shops, I'd say their pricing is in line with what you'd expect from a shop that uses the right parts and does an exceptional job of installation & servicing. There's a great deal of automotive expertise in their employees and Chris himself told me he works hard to treat them well in order to keep them. I've long known Muffler & Go has a great reputation and I now know why. Their business name is Muffler & Go but it is obvious that they do much more than exhaust systems. I'm one of their newest customers and I can say I'm 5 star satisfied so far.
