Frequently Asked QuestionsAnswers to some frequently asked questions about auto repair and maintenance.
Why do I need to have my fuel injectors cleaned?
Over time, a buildup of fuel deposits can cause partial blockage of the fuel injector. There is also often a build up of carbon on the back of the intake valve and in the combustion chamber. This buildup can cause uneven combustion to occur. The carbon buildup on the back of the valves can act like a sponge soaking up fuel before it makes it to the combustion chamber. This starves the engine for fuel and can cause hesitation on acceleration to occur. The carbon buildup on the top of the piston can cause an increase in compression. This can cause pinging or, on newer vehicles, can cause the computer to retard the timing to compensate for the pinging (thus less power and worse fuel economy). Carbon is also a gritty substance that can accelerate engine wear as it flakes off and is circulated in the engine oil.
Fuel injection cleaning can eliminate many of these problems before the buildup becomes extreme.

How should I prepare my car for an upcoming road trip?
Prior to going on a trip, you want to ensure that everything is in working order and not ready to fail on you.
Check all lights. Check your headlights (high and low-beam), brake lights, turn signals, parking lamps and (if you have them) fog lights to make sure they are all operational. You should clean your headlights using glass cleaner to improve night visibility.
Check wiper blades. Inspect them for cracks or tears, and make sure they’re operational. If they’re in good shape, it’s still a good idea to clean the rubber blade with little glass cleaner.
Check all hoses. Look for any cracks or holes in hoses, and replace any that are not in good shape.
Check all belts. Inspect all belts to ensure that none are worn, loose or frayed.
Inspect the battery. If there is corrosion on the terminals, you can clean it away with a toothbrush and a pasty solution of water and baking soda.
Check all fluids. Check the reservoirs to ensure that your coolant and wiper fluids are at the proper levels. Check your oil using the dipstick. Check transmission fluid, power-steering fluid and brake fluid. Refer to your vehicle’s owner’s manual for advice on checking all the fluids.
Check your tire pressure. Ensure optimal tire pressure so that you can save on gas during the trip.
Why do I have squeaky brakes?
There are a number of reasons why your brakes can squeak, but you should be concerned when the squeaking or grinding sounds become continuous. This usually means that it is time for new brake pads and shoes. If you notice any of these problems, then you should get your brakes checked as soon as possible. Worn brakes can mean longer stopping distances and difficulty stopping in emergency situations. Rotors and drums that are too thin may even become over-stressed and break.
How do I know when my car needs a tune up?
You can look for certain signs of decreasing performance in your vehicle, such as a decrease in your gas mileage. Your vehicle may start running rough. If your check engine light comes on that could also be an indicator that your vehicle needs a tune up. The owner’s manual that came with your vehicle may suggest a tune up at a certain mileage point as well.
