I would hate to go to the dealer and give up my left arm. Anything would help. Thanks alot. |
Are you sure it is a P0171 this time?
Look for a vacuum leak or Did you accidentally fill up with E-85 fuel?
Make sure the 2 hoses that go to the air cleaner lid and the VSV are properly connected or you will suck RAW fuel or fumes, this will set a P0171 lean code.
