    Hello and thank you for taking the time to read my concern on my vehicle. I have a 96 Acura integra ls non-vetch and I’ve been having a code p0171 For the longest and I can’t seem to figure out what it could be I’ve changed out the fuel filter, fuel injectors l, spark plugs, spark plug wires, got a new header with new gasket. I have sent it in to the mechanic shops and no one can seem to figure out what’s wrong with it. I need help and my car is almost due for smog can you help? At least point me to the right direction thank you in advance and thank you for all that you do I love watching your videos, keep it up bro.

    Considering the parts already changed, you might look into the following.
    Dirty or faulty mass air flow sensor
    Vacuum leaks – PCV hose, vacuum hoses, intake manifold gasket.
    Weak fuel pump
    Exhaust leak
