What does the check engine light mean?    

The check engine light is designed as an indicator for a larger issue. When the light goes on, it means the computer in your vehicle has determined a system or component in your emission control system isn''t working as it should. When the light comes on, one or more codes are stored in the engine control model so technicians can determine the exact problem.

Look for a serious problem: Check for anything that may require your immediate attention. Look at your dashboard gauges to make sure your engine isn''t overheating, or that you have low oil pressure. If you do notice either of these problems, pull over and shut off the car right away.

Tighten your gas cap: Check to see if your gas cap is tight. Many times, this is a quick and easy fix to the solution.

Reduce your speed: If the light is on and there are noticeable performance problems, slow down immediately. If you''re pulling anything (i.e. a trailer), lighten your load as much as possible and stop towing until you can get your vehicle to a repair shop.

If your car has started pulling to one side or you feel your steering isn''t the want to play around with your steering. Your and your passengers'' safety is at stake. You want to be able to confidently make turns and steer clear of danger on the road. If your steering''s off, you may be putting yourself in danger.

Some signs that your steering and suspension may need to be looked at include: 

  • A vibrating steering wheel when you''re driving at high speed
  • Loose steering that may wander off to either side
  • Feeling every bump in the road as you go over them
  • Excessive noise when going over uneven terrain
  • Loud screeching while parking or going at low speed

Stop by The Muffler & Auto Express and we''ll get you in and out in no time. Don''t let a small issue escalate to a major repair. Bring your vehicle in and we can assess the problem. It may be a lot smaller than you think! 

Remember that steering and suspension parts can and do wear out. To maintain the safety of everyone in your car, get a diagnosis from our expert technicians. And we''ll get your car back on the road so you can enjoy it again.

Starters
When you turn on your ignition, the solenoid receives electricity from the car battery and then engages the starter with the flywheel.

The starter turns the flywheel, which turns the engine crankshaft, which in turn starts the motions of a running engine.

Alternators

An alternator creates a current by spinning a magnet around at high speed, then running the current through a current rectifier. A rectifier changes alternating current (AC) into direct current (DC), enabling the alternator to produce power to run all the electronics in the car and charge the battery. 

To remain in the best control of your car or truck, have the shocks and struts replaced when they become worn. The shocks and struts are part of your suspension system. They allow you to experience a smooth ride as opposed to being jostled as your car navigates an uneven road.

Your shocks and struts are part of what makes you able to handle your car and drive in comfort. There are many factors that will influence how your struts and shocks wear and last. Some of them include the speeds you drive at, the conditions of the roads you travel and even the weather and how much weight is in your car. So be sure to have our technician check to make sure your shocks and struts are not worn out.

Some signs that your shocks and struts may be worn include: 

  • Excessive noise after you''ve gone over a bump in the road
  • Your car pulling to one side when you drive
  • Bouncing over the slightest dip in the road
  • Your car rocking back and forth after you come to a stop
  • Swaying from side to side while changing lanes

These are just some of the times when it''s wise to have your shocks and struts checked. The importance is not only for your own comfort, but these all- important parts of your car are what help your tires stay connected with the road. If you''re slipping when getting off the highway or going around a curve, don''t take any more chances.

  • Low Pedal: If your brake pedal nearly touches the floor before the brakes deploy, you may need a simple adjustment – or, it could indicate something more serious.

An exhaust system can provide better gas mileage and noise reduction. We provide high-quality mufflers, pipes, and exhaust system components. Read on to understand how our service offering works for you.

Gas Mileage

The exhaust system is an integral part of your vehicle; keep it running smooth and get better performance by replacing your muffler with an exhaust system geared for efficiency.

Although efficient performance ends with exhaust emissions, it begins with air intake. Any resistance through this channel puts a damper on your vehicle’s acceleration. If your air filter is inefficient we recommend a replacement or a high air flow filter.

Noise and Emission Reduction

The muffler safely transmits fumes of burnt gas away from your car. Before those gas-fumes exit the muffler, environmental regulations require filtering through your vehicle’s catalytic converter. Regulations require emission control, but that doesn’t mean you have to settle for restricted air flow. We install catalytic convertors, made from durable materials, which meet legal requirements in 49 states and pass EPA regulations. Although we install a variety of manufacturer products, the most popular are MagnaFlow and Flowmaster. Quality workmanship and great products result in an installation that lasts for many years, without declining performance.
