[QUOTE="Brian H, post: 1451715, member: 16038"] Im asuming its a bad fuel pump under load. It is running really lean and when watching it on the cheap scan tool it shows that its requesting fuel on rev but its not getting it . The plugs are white so it isnt getting fuel. Im hoping its the pump or Im going to have to get the ecm flashed. The new engine had everything on it so its cant be a bad sensor. Only thing left is the fuel pump and ecm from the old engine.
