Symptoms
Loss of power, erratic idle (more so when cold) boost spikes (loss of total power during overtake), excessive smoke under hard accelration etc.
If you contact Nissan and say your having these symtopms with your car, they will probably say you need a new diesel pump but that’s not really true or not always the case.
With a new car you get new issues one of mine was a faulty key fob like most of this type the covers and buttons fail break split etc. It’s not as common on the older fob but the newer style from 2000 on till about 2004/5 is quite bad. This fob is widely used across the full Nissan range.
i’m using a Engine loom and ecu (23710-74F01) from a 1996 200sx (S14) But with the added benefit of having it fully programmable.
