Baffled
I have a 97 passport, I cleaned the tank well, changed the fuel pump and
filter, checked the fuel pressure-44lbs, so it's good, manual calls for 42-56 so
I'm in the range. changed the purge box and silinoid, and I still can't have the
gas tank above half or the engine stumbles at midthrottle, half or less, it runs
great, plus I can't have the cap screwed tight or it will leak gas out the vent, I
changed the cap, and still the same...now what?
