I have a 1998 k1500 with a reman. 5.7 with about 7000 miles on motor. Before I replaced the motor had a engine miss with p0300 code. After engine was replaced still had code so put new wire, cap and rotor, miss and code went away. Now I have miss back but no code. Also replaced intake temp sensor, throttle pos. Sensor, map sensor, cat. Convertor, engine coolant temp sensor. Tried plugs and wires again, went away for 1 day then come back. The intake gasket is new, I think I have rule that typical problem out, (issue doesnt go away when warmed up). Please give me any ideas, I love my truck but am starting to get frustrated. Btw engine was replaced with 210,000 miles and had developed a knock in the bottom end
have the same problem?
