After my initial rebuild I started the car and only ran it for about 5 minutes. Well, long story short -> Nissan took about a month and a half to rebuild the motor. After I got my car back from Nissan and had ~100 miles on it one of the injectors stuck wide open. I sent all of them to RC and had them checked and they came came back all fine. The guy said the test solution must have unstuck the problem child.
