My check engine light came on yesterday and I went to Auto Zone to pull the code. Well, the codes he they pulled were P0170 and P0171. He said it could be the intakeor the exhaust, but didn't sound to sure of himself. So, now I'm here hoping you guys could help me out.

i couldnt find a170 code bt the 171 code is system lean, usually means a vac leak, plugged injectors ,worn o2, i would check for vacume leak first.

I think it might be my injectors. because on a full tank of gas, im only averaging about 170 miles to the tank. I thinks thats pretty f'ing low. could this be the problem? if so, how to I clean them/what injectors do you guys recommend if I buy new ones?

check your oxygen sensor first. if it fails the ecu thinks its running lean and is trying to richen the fuel mixture,hence the bad gas mileage.
