i pulled the codes on my car, i got a 171 and a 174, both banks runnin lean, im kinda new to this car, any idea how to fix, injectors, o2's, fuel pump, i just cleaned the injectors but havent drivin the car yet to seee if it worked, just thought u guys would know more than me, maybe this is an easy fix, maybe not, any help would be awesome

 

I'm smelling new coils...........

 

my coils are pnly a few months old. i hope not

 

Code 174 dont exist. It will be most like 171 and 172. But both of those show a few causes.

Either manfunctioning O2 sensor (hard to see when both come up)

Injectors going bad or clogged (pour some nice chevron injector cleaner in there)

MAF sensor going bad. But that will throw a MAF code of 100 unless it is throwing very low numbers and messing with the system. But even then it can get a malfunction code.

Id get the injectors cleaned up first. Clear the codes and take it for a ride.
