Message It was running rough and fuel was literally dripping from the passenger side header. All the injectors ohmed in spec. I confirmed spark and swapped around coil packs with no change. I did a power balance test and 1 cylinder was definitely not firing on the passenger side but one other was suspect as well. Though the engine seemed to be running on 5 not 4 cylinders. So I swapped all 3 injectors from either side and got the fuel leak to move to the DS. So I'm thinking at least one injector has failed open though it's strange they ohm in spec.

I'm thinking about ordering a set of remand'd injectors from Rock Auto as suggested above.
