Possesed VehiCROSS

Having just gone through the P0171 code with my old Geo tracker, this code is usually due to a vacuum leak somewhere. Check the hoses and especially the EGR valve diaphragm and the charcoal canister. Even a small leak will set this code. Another cause is a bad O2 sensor.

Have you been using an injector cleaner lately? Since your code came up as "lean" you may have the same trouble as a few others where #1 bank has foulded or clogged. I always run injector cleaner through about every three months and make sure my gas cap is screwed on tight(this also will give you a code reading). Also check for vacuum leaks near the top of the engine.
Good luck...John
