    Engine Tune

    Okay, so I have had my SS for like 3 years now and I guess the previous owner never tuned the car after he installed the Dynatech headers along with the Borla adjustable catback system. I am assuming this is why my SES light has always been coming on since then giving me a P0171 code? I check the reference of the code and it always says something about my airbank #2. I haven't had the car tuned yet. Is it necessary though? If I don't will this light just continue to come on over and over? I feel like it is making my car run a little lean though. If your car runs lean too much is that bad?

    the p0171 code means you are lean in bank 1 and p0174 code is a lean in bank 2. Do you have both codes? or Just the one? For me I had a vacuum leak in the tube that goes from the EGR to the intake manifold. The light won't just go away. I am not sure if it is bad if it runs too lean for a long time but I would just fix it so you don't risk it.

    Mostly it is just P1071, but I occasionally get the 1074 code too.

    Running lean is bad. You should get a tune with headers, but your problem might be something else like low fuel pressure or a bad MAF sensor.

    Agree with all that has been posted. Is the MAF stock?

    It has to be pretty lean to throw the codes - first thing I would check for is a vacuum leak. Would be a good idea to get some logging on it to see what the fuel trims look like...

    I don't think the fuel filter has ever been changed. The MAF is also stock.

    Certainly won't hurt anything to change the filter then. If you don't find any vacuum leaks, maybe check your fuel pressure at the rail. You should have right around 58 psi.

    Alright, I will be sure to check those things out when I get it in the shop next time. Currently waiting on some money to fix some stuff if you catch my drift.
