So i think I know why my 300zx is running like crap. I initially ran codes and got a 55 and so I couldn't figure out what was up... I ran the codes again after i ran it for a few minutes and sure enough i got a code 34. I went to look at the detonation sensor and sure enough one of the wires had come out of the connector at the top of the motor. So my question is, can i soder this connection back is there a way to relocate this without having to tear the entire top part of the engine. I have seen workups for a bypass... obviously i would rather have this working than bypass.
