Swapping the wires will lead to the timing being slightly advanced, the sensor sending a miss reading to the ecu.
This was an early Nissan fix 96/97 for what they termed as bunny hopping.
Should help to eliminate the sensor in the injector as the problem
Thanks Toolbox :smile: So if swopping the wires sorts the prob out can it just be left like it or do you have to replace the sensor & injector :? sorry for all the queastions just have never had a dirty D before getting the T2 :roll: give me a SU or Webber carb & i'm fine :lol:
