I have a 1999 jeep grand cherokee laredo and has over 250000 miles on it. A code p0171 is up. It says that it is running lean in bank one. I can't figure out what the issue is with it. I replaced the mass air flow sensor and the fuel filter so far

If it runs Lean on one side and not the other the problem only exists on that side such as a vacuum leak on that side a head gasket leak on the outside or fuel injection problems on that side only
