This code usually denotes air/mixture control fault. Whoever read off your error code should be able with diagnostics equipment to be more precise than just a code. Its possible that your MAF sensor, mass air flow sensor could be at fault, located on top of your induction piping next to your air filter box. Make sure you check the basics first before allowing anybody to empty your wallet via guessing. Check all your induction piping for splits or collapsing under load, aswell as your air and fuel filters for condition ie: when wheir they last changed. Hope this starts the ball rolling for you. Most of the above are simple basic things you can check yourself before paying out money to the experts. Rule of KISS.
