I have a 2007 Expedition El with 142000 miles and I started getting a rough idle with a P0305 code. I replaced the plug and fuel filter since I wasn't sure about original owner. Still had the code so I replaced COP on #5. Engine still runs rough with no power and throws intermittent P0300, P0305, P0307. I have switched injectors and codes don't change. Attached is the Freeze frame data from my scanner. I have to tic from the cam phasers. Could they cause this problem? Fuel trim levels are way different on the banks. Any ideas of what would cause this?
