I bought a 97 ram 1500 with a 318 5.2l engine it drove fine when I bought it but the next day I crunk it and when I started accelerating it acted like it was killing the engine it made a popping noise in the engine and it kinda had a jerking feel to it but I let off and it idled fine but I had to feather the petal to get it to go and then it kinda calms down when I get up to a highway speed it just randomly jerks I've look at the wires the coil the plugs the distributer I've listened to the injectors and I've taken the throttle body off and cleaned it and I've replaced the fuel pump and the pre cat o2 sensor The engine light is on and the codes are p1763 po713 po711 but I didn't think the would be the cause of this.
