i have one of the scanners that Advance Auto Parts uses(b/c i work there) i also have a book to it for the codes, if you tell me the code numbers i can look up the codes and tell you what they mean most probably. but yes take samples of your gas and then gas from a diffrent store. also change your fuel filter. and also put some kind of addative to clean your injectors and what not like Lucas Fuel Treatment, or the STP or GumOut.
