Hello I am new to mustang forums. I have a 2006 ford mustang gt. I have p0053,p0054, p0059, p0060, and p0443. I’ve changed all spark plugs, all coil packs, all injectors, purge valve, both cam shaft position sensors, all harnesses for injectors, coil packs, timing solenoid, all 4 o2 sensors, changed the brake booster check valve and vacuum line from check valve to fuel rail. Maf sensor is good. Codes keep changing but goes back to pre-existing codes after replacing stuff. Those codes above are for o2 sensors and cam shaft position sensors but they are all new. Engine has a rattle after warming up in gear and almost stalls the car. And sluggish on acceleration. Sounds like a misfire but strange with all new parts. Any suggestions are welcomed and appreciated thanks!
