So I decided to just put a motor in it, we did the swap and the new motor does the exact same thing. Only things we havent changed arr the computer the o2 sensor and the fuel pump..could these be the culprit? I bought the truck for 500 and now have 1000 into it..all for nothing. This is rediculous

Thanks man. Apparently it was the o2 sensor the WHOLE time! All i did was unplug it and it runs pretty good now..not perfect but driveable. Stupid 4.3
