Have Ford Questions? Ask a Mechanic for Answers ASAP
Hello and thank you for your question. My name is James.
Given the symptom and behavior of the vehicle, have you had a chance to check the fuel pressure yet? Low pressure will cause what you describe. You'll want to see 33 psi minimum. We can chat back and forth here until we get to the bottom of it.
Ok thank you. Can you tell me what mass air flow sensor readings you found?
Can you also look at the BARO reading and let me know what it is?
Okay thank you. The Baro reading indicates a geographic elevation of about 4600 feet above sea level. Does this sound correct for your location?
