Yeah, all the sensors have correct readings based on Forscan. It passes the Key-on-engine-off test and the engine-on test.
Started today after 8 seconds of cranking and some light gas pedal. I shouldn't have to do that in a fuel injection vehicle.
So not clear what the malfunction that's still there. Clean the throttle body? I have been running it a lot with fuel injection cleaner. Why does it need the gas pedal to be engaged to start? It doesn't look like it can start without light throttle and has always been like that for the last 2 years.
Today the idle was a bit weird, steady, but when I hit the gas, I could not rev it up to 3,000 rpm, it barely made it 2,000 and the tach wanted to drop. I remember a week ago when I was able to start it for the first time in months, it would readily rev to 3,000 if I wanted to.
The first thing it does when the throttle is hit, the rpms drop a bit, then go up. Maybe it's the gas? Maybe I put too much fuel injection cleaner? I got the gas yesterday in a container and poured it in.
all in all it does much better after the crank pos sensor swap (which BTW was never flashed as having an error, the mechanic I got swapped it after a hunch). Nothing in Forscan, his Ford scanner or my scanner. But still, the perpetual problem of "Easy start when hot, difficult start after sitting overnight". Is it a Ford V10 thing? An undocumented feature?
