The codes P0171 and P0174 both indicate that the engine's air-fuel mixture is running too lean. Here is a guide to help you fix it but I can tell you a clogged fuel filter, vacuum leak or a bad MAF sensor can cause this problem.

Here is the locations for the MAF sensor and fuel filter. Check out the images (below). Please let us know what happens.
