Spark plugs are what ignite the air and fuel inside an engine’s cylinders. This allows your car to start and keep moving down the road. Most people don’t know that much about them. Here are 6 indications that they should probably be replaced:

Your car shakes when parked:
Your engine is supposed to run at about 1000 rpm during an idle. When the spark plugs malfunction, this goes up significantly. If this happens to you, take your car in immediately; it can cause costly problems.
Your car won’t start:
Malfunctioning spark plugs are one among a few reasons for this. They are necessary but not sufficient for getting your engine to start; without them it just won’t happen. When your spark plugs aren’t working correctly they can drain your battery, another reason your car might not be starting.
Your engine misfires:
If your engine stops and starts over and over, it is misfiring. The cause of this is a malfunctioning cylinder, probably due to the spark plug. This can make emissions shoot up drastically.
Your engine surges:
A surge is when your vehicle slows down, starts and stops, or jerks out of nowhere. Excess air created from the combustion process is what causes this. It is unsafe to drive if your engine is surging; it can potentially cause a wreck.
Your car uses more gas:
Fuel efficiency can decrease by up to 30% if your spark plugs aren’t working properly. If you notice that your car is using more gas, take it in as soon as possible to avoid throwing money away.
Slow or delayed acceleration:
Faulty spark plugs can cause both of these problems; while they may not seem urgent, your car should be taken in immediately if you notice them.
All of these signs are a good indication that you should bring your car in to be checked. If you suspect something is wrong, don’t wait; stay ahead of repairs.

In a time when gas prices seem to only increase, improved gas mileage is a huge benefit of having a tune-up performed on your vehicle. A tune-up involves replacing old parts such as spark plugs and air filters. A dirty air filter can reduce your gas mileage by up to 20%! So having these simple parts replaced can save you at the pump.
No one wants to be stranded on the side of the road because of car problems. And the price of having your vehicle towed can be outrageous. Having a tune-up performed routinely can save you from this headache. Tune-ups help keep your car reliable and trustworthy on both long and short trips.
Having routine maintenance performed on your vehicle increases the value of your car. If you ever decide to sell your vehicle it will help you immensely if you have maintenance records on hand. Any buyer will look favorably on a car that has had tune-ups performed regularly.
With the official start of summer on June 21, many people across America are gearing up for a summer road trip. But with gas becoming increasingly expensive, you may be looking for ways to ensure your car is as fuel efficient as possible on your upcoming trip. So if you are living in Mission Viejo and are packing up for a summer drive across the country, consider these tips on how to get better gas mileage on your summer road trip.
Some have said to picture an egg under your gas pedal while you accelerate. Aggressive driving where you slam on your brakes and punch the accelerator frequently will destroy your gas mileage. Cutting down on your aggressive driving can save you not only gas money, but also can save you from getting involved in accidents.
One of the number one reasons people suffer from poor gas mileage is because their tires are not properly inflated. Be sure to check your tire pressure against the manufacturer’s recommended PSI. Under inflated tires can cost you countless dollars in gas money and also can pose a risk for rollovers and other accidents.
