Have Ford Questions? Ask a Mechanic for Answers ASAP
Have you checked the fuel pressure under load? We have had quite a few fuel pumps that were defective from the factory.
are you sure the code is P029A, I cannot find that code listed?
Have you checked the O2 sensors for bank 1? To see if it is reacting properly?
The readings will vary, just watch to see if they are switching between rich and lean, and the down stream sensors should be fairly steady.
