Hello all, I have been a long time lurker and finally decided to create an account and make a post to ask for help. I have searched everywhere, every thread related to P0171 & P0174 codes but I could not find anything that was close to how my FJ has been acting lately. Here is what happened:
HI, I have a toyota fj cruiser 2008. The problem is the motor hesitates and emissions are black. I have the code p0174, when to shop and they change, fuel pump, fuel presasurre regulator, maf, spart plugs, filters. and the problem still. I dont know what else to do.
