Went to Autozone and had a CEL checked out with the codes P0171 and P0174. The employee said that it's probably the MAF sensor and quoted a price of around $105 with a core charge of $45. I thought there was a way to clean the sensor with electronic parts spray. I will be selling the car later this year, but would like to get rid of the CEL.
