Hello, I bought a mustang 2008 4months ago and I am facing lean code since then. I got it to a mechanic who changed the maf and fuel filter but nothing worked. Then I went to another one who changed the O2 sensors same problem. I then replaced the fuel pump and fuel pressure sensor regulator by myself still the lean code appears, but the trims were changing when I first drove the car for 5miles then it went to lean. There is no leak vaccum leaks. The short terms in range of 0 to 10 but long...
