have a 1994 nissan hardbody truck v6 3.O liter. Replaced timing belt,waterpump,pulled injector rail with all six injectors cleaned and tested. Code comes up injector problem we also had new plugs wires o2 sensor. Problem is we can only get 9 to 10 miles per gallon of gas. has a slight lifter tap but does not miss. Could the injectors be putting to much fuel in intake? Or could fuel pressure regulator be causing it. Decent truck but at ten miles per gallon not real practical to keep. Could anybody reccomend and suggestions. Thanks you.
