damn engine code too lean
Ok for the past 2 months my car has been throwing the P0171 code which is fuel system too lean.....someone told me it is a vaccum leak or air entering after the MAF...i checked the whole inlet tube for leaks and changed the throttle body gasket and it is still throwing the code after i dissconnected the battery...any other things it could be?

Check your MAF sensor, fuel filter (may be dirty and cloged causing less fuel to be delivered to the injectors), fuel pump may be bad, and the stock fuel pressure regulator may have a problem. Look at all those then get back with us.

I had the same issue a few weeks ago when I got some bad gas. Filled up with good stuff, ran it a bit and cleared the code with my Xcal, code hasn't popped up again.
