I have replaced the injectors. It’s giving me the 34 code as well as the code for detonation sensor. The knock sensor has been relocated to the back of the motor. Is it normal that the plug going to it has two wires then at the plug tot he knock sensor only one? I’m just not familiar with this and when I remove the plug from the knock sensor is it supposed to change anything like with the idling of the motor? Nothing changes!
