well went to autozone and the pulled p0171 and p0174 i know this is lean in bank one and bank two i thought is was bad o2 sensors but he said it was ether clogged fuel injectors that i already put b-16 in to clean or a dirty fuel filter he told me to replace it or mabe add an additive or get a higher octane i already use power plus so what are your suggestions you guys are the most reliable source i feel like every one is a mechnic here so what should i do

Do you have a aftermarket mass air meter on the car? If you do take it off. If not try fuel filter.

 

anyone know how hard a fuel filter is to replace and no aftermarket MAF

does this sound like the fuel filter is the problem or somthing else any suggestions would be helpfull i don't want to go replacing things that aren't bad just to still be greeted by the SES light in the morning any other things i could do

thanks for the help

 

You have a 5 year old car. If the filter is original change it. Put a fuel pressure gauge on it. See if the pressure falls off at wot. It could be filter ,fuel pump bad stock mass air meter.check it all and spend some money on maintance.check to see if the filiment on the meter is good and clean.

 

ok after all day of thinking what could be wroung with the car and almost narrowing it down to needing a fuel filter i remeber that it used to make a pretty loud whinning sound from the gas tank wich makes me think it could be a fuel pump but since the noise has gone away what do u guys think is it a filter or a pump causing the codes and how much does a fuel pump usually run price wise and getting it installed i need to get this fixed but am tight on cash seeing as how i just got the car painted anu in depth info would be greatly appreciated
