The 3.8 is so much easier to work on than the vq40de my brain hurts after 2 days of testing stuff we spent a total of 11 to 12 hrs testing things, pulling things apart and reassembling. To top it off the forums suck for the pathfinder/xterra/frontier. I've posted all this same stuff over on the other forums and I haven't got any help. I can't afford to replace the pathfinder without having to sell the gp so I hope we can figure it out.
