Well this does not have to do with an idi but this section gets the most traffic and you guys seem to know quite a bit. Today I brought my fathers 2001 f350 5.4 through emissions and the test guy revved the **** out of it and the truck stalled and wouldn't start without a jump. Now the od light flashes until I start moving and first gear slips then shifts hard to second. Then it drives fine until I stop again. I managed to get it home and now it doesn't start without a jump every time.
