  • F250 issue

    Hello Crew. I have an 06 F250 which has been giving me issues for months now and I am at a loss. Started off with it running poorly. Discovered a bad fuel pressure regulator. Replaced the regulator and ran fine. Ran the engine in a tank 4-5 times and it seemed fine. Dropped it in the water and it immediately ran poorly again. Rough idle and no power up top. Replace the fuel pumps, injectors, and plugs. Been through the VST and all fuel lines. Also replaced the pulsar coil. Verified all injectors and coils are functioning. Ran the engine on a remote fuel tank and no change. The symptom now is when the engine is first started it runs ok for a few seconds then starts to run poorly. I will try to upload a video. After about a minute it runs better. Discovered a diagnostic code 0007 but it’s not defined. There are several sensors that seem to be out of spec. Throttle position sensor 1&2, throttle valve opening, accelerator position sensor 1&2 but no codes. What could cause all of these sensors to be out of spec? Any help will be greatly appreciated.
