After getting everything done the thing started and ran like crap until it decided to not start at all. So I decided to start from the begining and have the computer rebuilt. After getting the computer in it started right up but still does not run well. It will idle smooth at about 2k for 20 sec and then fall down and stumble around 800 for 20 sec and then rev back up to 2k and back and forth until it gets warm. Then it stubbles as it revs and just runs generally crummy. I have converted this thing to 3.0 injected and have replaced wiring harness, engine and trans, gas tank, fuel pump, you get the picture. In looking through the books I realized that the oxygen sensor was missing from the donor truck and so I don't have one hooked into the system. The computer shows no codes and the check engine light is not on. Here is the question. Will no feedback from the ox sensor make this thing do what I am seeing? Will it run without one? Unfortunately the pipe that the sensor screwed into was missing on the donor. Converted a 89 2.6 4x4 into a 91 3.0
