I just had the same issue. Cost me $40.00 to find out my gas cap wasnt clicked all the way. He also said that after the error arises, simply closing the gas until it clicked may not have removed the error code from the computer. Not sure how, but you might have to reset the computer, maybe just pull the battery?

more than likely your mass air flow sensor is bad. it is located. on the air fliter box to the right of the box lid. cost about $200.00 at the dealership. go to autozone or advance and you can the same thing this one is a refurbished one for half to cost. un plug sensor. un screw two phillips screws, pull it out and put the new one in. thats it. good luck
