As you can see, a regular tune up is important to your car's performance. The process should involve replacing the air filter, replacing or cleaning the spark plugs, and replacing the distributor cap and rotor. It can also include replacement of the spark plug wires, fuel filter, PCV valve, and oxygen sensor.
Beginning in 2007, daylight time starts on the second Sunday in March and ends on the first Sunday in November. For a very readable account of the history of standard and daylight time in the U.S., see. Ian R. Bartky and Elizabeth Harrison: Standard and Daylight-saving Time, , May 1979 (Vol. 240, No. 5), pp. 46-53.
Daylight Saving Time (DST) started at exactly at 2am on Sunday March 12 as the clocks sprang forward one hour, making it 3am. The mornings will get darker and the evenings lighter and those living in participating states of the United States will lose an hour in bed.
