Hello, I'm new to this forum and need help solving this mystery. I have a 2006 ford expedition XLT with no codes, I changed spark plugs and coils, cleaned the MAF sensor and throttle body, checked for vacuum leaks with no luck. Took it in to have it diagnosis and test the fuel pressure which is 28-45. and told me fuel pump is losing pressure and i should change fuel filter and fuel pump which i did and now it seems like it got worse. Does anyone know what it can be?
