INPUT ARTICLE: Article: Many problems that can come up with your vehicle prompt warning lights on your dashboard. Pay close attention to any that come on and what they do, so they can help you determine what the issue is. A flashing check engine light usually means your engine is misfiring. Having misfires occur when the engine is under an increased load (like when going up hills) is a fairly common problem. You should also look for any warnings indicating high temperature (if equipped with a temperature light) and low voltage (which looks like a battery). If the check engine light does come on, plug an OBDII code scanner into its port found beneath the dashboard on the driver's side. It will look like an open trapezoid shaped plug with rounded edges. Then turn the key to the accessory position on the ignition and turn on the code scanner to scan the error codes. The error codes will be a combination of letters and numbers, but most code scanners will also provide the English description. If your scanner doesn't show the English description, write down the code and find it in the vehicle's repair manual or on the manufacturer's website. Many auto parts stores will scan the error codes in your vehicle for free. If you can hear an audible sputtering coming from your engine or the exhaust, it's probably a sign that one of the cylinders in the engine isn't firing properly. You may need to get out of the vehicle while it's running to hear it. Sputtering will often be accompanied by a flashing check engine light, but it doesn't have to be. Make sure you only get out of your car while it's running when it's safe to do so, and with the vehicle in park (or in neutral with the parking brake engaged for vehicles equipped with a standard transmission). The head gasket is a seal located between the engine's block and cylinder head. If it goes bad, the engine will suffer a loss of compression, which will really reduce the power it can produce. Blue smoke in your exhaust is a strong indicator of a blown head gasket. A blown head gasket can begin as a pinhole and grow in size and severity quickly. If you see blue smoke coming from your exhaust, stop driving the vehicle immediately. If your engine is overheating, it will almost certainly stop producing as much power. Many vehicles will enter "limp mode" that limits the engine to a certain RPM to protect it from damage, but others may experience power loss because of damage being done by the heat. Your temperature gauge will have clear indicators for hot and cold, as well as a middle range that's considered normal. If the indicator goes out of the normal range and points to "hot," the vehicle is overheating. A severely overheated engine can warp the cylinder head and drop compression in the piston cylinders, permanently reducing power output. Overheating may also be a symptom of other issues, which when combined with other symptoms you notice can point you toward the problem. If the code scanner indicated an issue with a particular cylinder, disconnect the spark plug wire from it, then remove the spark plug. Insert a compression tester gauge where the spark plug was, then turn the motor over 4 times. Write down the compression rating, then repeat the process for each of the other cylinders. If there's a compression issue with the cylinder, the readings on the gauge will be much lower than it is for the others. A loss of compression may be caused by failed piston rings, a blown head gasket, or a number of other issues, but all of them will likely require removing either the cylinder head from the engine or internal work in the engine's block, all of which may be best left to professionals.

SUMMARY: Check your dashboard for warning lights. Use a code scanner to read any engine error codes on the dash. Listen for engine sputtering. Look for a bluish hue in your exhaust. Make sure the engine isn't overheating. Do a compression test on the engine to determine if an issue is internal.

In one sentence, describe what the following article is about: In most basses, the truss rod is located at the bottom of the headstock. Some bass guitars, though, will have the truss rod hidden at the bottom portion of the fret board where the neck joins the body. If the truss rod is in the headstock, you should be able to make adjustments with a 5mm Allen wrench, which should be included with your bass. If it does not have one, you should be able to get one from a tool kit. If your truss rod has a cover on it, it'll need to be removed. You will see a metal plate screwed into the back of the bass where the neck joins the body. This can be removed by simply unscrewing the screws that are fixing it to the guitar. Remember to keep the truss rod cover and its screws in a safe place. These truss rods can be adjusted using a Phillips screwdriver. A good rule of thumb is the thickness of one to two business cards between the string and the frets. More experienced bassists will probably have a more specific gap in mind, and can adjust to that. Frets are the ridges on the neck that you press the strings onto to create different notes. Slide the business card between the string and the 8th fret (starting your count from the headstock). If the card can't fit, you'll need to loosen the truss, and if there is extra space, you'll have to tighten it. In most basses, you will turn the rod clockwise to tighten the truss rod, and counterclockwise to loosen it. You shouldn't need to turn it much, about 1/4 turn in the necessary direction. Clockwise and counterclockwise directions based on looking down the neck from the headstock. Once you have made the turn, check the gap with your business cards at the 8th fret again. Avoid adjusting more than 2 or 3 times in total. If you still aren't satisfied with the adjustment, or notice you can't turn the rod any further, take it to a professional technician to let them examine it. Once you have finished setting the truss, retune the strings and let your guitar sit for a few hours. You want to let the wood settle after the adjustments. After the rest, pick it up and give it a try. If everything feels right, you are ready to go.
Summary: Locate and remove the truss rod cover. Check the gap between the strings and the fretboard. Adjust the truss rod. Check the adjustment. Let your guitar rest.

INPUT ARTICLE: Article: For example, if you don't like to spend a lot of time styling your hair, don't get a cut that requires detailed curling or blow drying. Do your research about what styles work for your hair type and face. While it's not impossible to have a good hair day with opposing hair types and styles, it does mean more work for you. Choose a style that you're willing to maintain and keep your hair at a manageable length. You might start having bad hair days when your preferred style grows out for too long. A great haircut that suits your face will grow out well and should make maintenance easier. Make sure you trust your hair stylist, especially if you're dramatically changing your look. If you're frequently having bad hair days, you might be overdue for a haircut. This is especially true if you notice split ends or limp hair that tangles easily. Maintaining your haircut every six to eight weeks will keep your hair healthy and tamable. This can prevent split ends that can contribute to frizzy hair. Seeing your stylist frequently is an added bonus. Not only will your hair get the treatment it needs, but you'll also build a rapport with your stylist. This can help when it comes to getting a last-minute appointment or dramatically changing your hairstyle. Your stylist should be able to recommend products for your hair type and style. Avoid using too much product, as it can build up and make styling difficult. Nourish your hair by waiting a day or two in between shampoos, using conditioners effectively, and avoiding damaging practices, such as daily flat-ironing or prolonged blow drying.

SUMMARY:
Choose a haircut that matches your styling and maintenance preferences. Get a good haircut to avoid troublesome morning hair. Get regular trims. Use the right products for your hair.
