So this is a newer truck with a ford lp in it. unit idles rough and then will go full rich and you would swear the smell will kill everyone in the building in a hurry.4
truck has 95 hours on it has had a new head installed due to a defect in the original head that was causing also causing a rough idle. unit has OEM plugs new o2 sensors even though post cat does nothing. as well as new injectors.
will run fine with a sweeping action on o2 sensor until it warms up a bit and then will go full fuel dump.
any help would be great
thanks
