As per JARblue, that code can be caused by many things. Some of the easier/cheaper things to check are:

Sparkplug condition. Pull each plug and inspect. Many pages on The Intertubes with descriptions and pics. You can make a decision about plug heat range after the inspection.

Clean the MAFs. Very easy job and something that probably needs to be done anyway. Several DIY threads on this site.

As per bcrider, make sure you have good gas in the tank.

Check for any other DTCs that may have been thrown. You can find OBD code scanners/readers as cheap as $20.
