I did a full top end rebuild cause the serpentine belt **** the bed and some strands got into the timing cover and it jumped time. So I got a good used used head and put a new cam, and lifters. I used the rockers that were in it. And my injectors with new o-rings. New fuel filter and timing belt, idler pulleys and tensioners, and serpentine belts. And it seems to stumble intermittently when driving after it gets to operating temperature. But does not if you are w.o.t. above 2500 rpm. I just put a new transfer pump in the tank last week and it didn't do ****. There is no codes when I put my scanner on it, and there is no black smoke, when accelerating either. Im stumped, any ideas from anyone that I should look at...
