My 2000 Nissan Frontier has sputtering problems and the tac goes crazy. changed the fuel pump, sending unit, spark plugs, cap & rotor. what could be wrong?
Your tach is run by the engine computer, possible cause. also by the crankshaft position sensor, most likely cause, I would start there. some sensors will run within perimeters and be bad enough to cause a lot of problems
