Background on what was done to car prior to codes.
I had LT headers installed and the before dyno was really low on power around 276 with FRPP cams, delete plates, C&L intake, and off-road h-pipe.
After header install picked up around 20hp with revised tune.
My car was not putting down expected power, so time to find out why. Changed plugs to no avail. A couple weeks later pulled front timing cover to make sure timing was ok, it was. Pulled plugs again to inspect and one of them looked lean, so figured maybe a fuel issue. Pulled all injectors and had them tested, cleaned, and flow matched. Injectors tested fine by the way. So figured might have been cams not making power for some reason and was about to put some comps in it. Well for testing put back onto dyno and picked up 26hp with just cleaning injectors. So maybe problem solved right?
Nope, after pulling the car off the dyno there were cam codes once restarted. Pulled sensors and cleaned them . Well drive the car about 60 miles no cam codes once car is restarted again there are cam codes again. The car is not running correctly either, it sound weird at idle, very sluggish, feels like miss fire at times, and slow to start. Reset and drive a few miles and codes come back again. Now they come on almost every time within first run, and if not second time starting. I have already changed the alternator and the ripple is well within spec. I have replaced both cam sensors even after them testing within resistance. I have had the timing checked also with Ford's IDS. Pulled one of the valve covers and the ford tech looked at phaser and said looked fine. I don't see any breaks in the wires. Ford is telling me they think it is the ECU. If it was the ECU shouldn't there be more problems? I have tried different tunes to see if that may have been problem and it isn't.
I am at a loss and have searched all over and haven't found anything.
Any help would be greatly appreciated.
