A faulty spark plug OR wire can be the cause of engine knocking, and is bad for your engine overall. Check for corroded spark plug ends. If a plug wire is left disconnected it has the potential to collect moisture. Did the previous owner let this happen and now months later corrosion has taken its toll? Remember to always check part numbers on the parts you buy. Find all of the tools you will need, such as a spark plug socket and gap gauge. Turn off your engine and if you think the vehicle will magically try to turn on during this process you can unhook your battery terminals. You want to be sure that replacing the spark plugs will help. You can usually tell if there is a problem just by the residue left on your spark plug. A normal plug should have only brownish grey residue on the side electrode. If this is the only residue and the plug is otherwise intact, you should just clean it with a wire brush and fuel injector cleaner rather than replace it. This is a relatively easy job but could take about 30 minutes to 1 1/2 hours depending on the design of the engine. Some plugs take just the right size of ratchet to fit into tight spots. Take photos to remember how parts of the engine go back on if they need removed to make the job easier. If you have never changed spark plugs before you should consult How to Change Spark Plugs in a Car Remember to do this in the correct order. First hook up the positive cable (usually red) and then the ground wire (usually black).

summary: Consult your owner's manual or a local parts store to find the correct spark plugs. Prepare to work on your vehicle. Check your spark plugs. Remove and replace your spark plugs an/or wires. Hook your battery terminals back up.

Sometimes, visiting the perfume counter can be overwhelming. To help you narrow down what you might like, try taking an online fragrance-finder quiz. That way, you'll have a place to start when you get to the store.  You can find a fragrance quiz by doing a simple search, but many major perfume websites also have them. You can also test out samples that come in magazines or ask people you know what their scent is if you like it. When you go to the store, you want a blank canvas, so to speak. Skip putting on any perfume that morning so it won't compete. Also, skip other items you use with strong scents, such as lotions and body washes. The first step to testing a perfume is spraying it on a card. Smell it when you first spray it, but also try smelling it again in about 5 minutes, once it's had time to dry and settle. If you like it both times, you can move on to the next test. Often, perfume counters will have coffee beans on the counter to help you clear out your nostrils. Take a good whiff between scents to help clear your palate, so to speak. Next, try it out on your skin. You may wonder why you have to smell it both on a card and your skin. However, each perfume interacts with your skin and body chemistry, giving it a unique scent, different from every other person who wears it. Therefore, you want to make sure you like the smell on yourself before you buy it. Consider leaving it on for a few hours before buying it. You may find you don't like it after having it on for a while.

summary: Try a fragrance quiz. Skip applying fragrances before you go shopping. Spray it on a card. Spray it on your skin.

You need to start with your cube in the solved position to make a checkerboard pattern. Also known as a chessboard, your Rubik’s cube will have a checkered pattern on each side when you are done. Begin by looking at the green side of your cube. Turn the right side of the cube two clicks forward. The three green squares should end up on the opposite side of the cube. Then, still facing the green side take the left side of the cube and turn it two clicks forward as well. Keep the green center cube facing you. Then, turn the top row clockwise by 180 degrees (two clicks). Turn the bottom row 180 degrees as well. With the green center block still facing you, turn the front face of your cube by 180 degrees (two clicks), as if you are turning a dial. Turn the back side of your cube by 180 degrees as well. You’ve now created a checkerboard on all sides of your cube.
summary: Start with a solved Rubik’s cube. Turn the sides. Turn the top and bottom. Make your final spins.
