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!

 

What brand of coils did you buy?

Bad dudes in the alternator are known to cause false cam sesor codrs. When they fail they create a lot of electrical noise. The cam wires and alternator feedback wires are in the same harness, thus the interference.

Do NOT get a cheap rebuilt alternator from the local auto parts store. They are usually bad out of the box or will fail after a short time. Get Bosch, Ac Delco, Motorcraft or Napa.

Rattle is probably timing chain guides, tensioners, and/or cam phasers. Buy only genuine ford parts for that stuff. Aftermaket garbage will fail.

 

I believe they were acdelco coils but I forget. I unplugged each one while running and each one dropped the idle pretty good. I changed the injectors. Are there different flow rates or all the same I didn’t check that when ordering and putting them in? Maybe gummed up? I’ve seen some say additives are bad and some say good. I was thinking phasers too. For all o2 sensors to pop codes gotta be something with combustion I would think. Thanks for your advice!
