Hi,i have a 2006 Nissan micra 1.2 petrol.It has started kangarooing as soon as the engine gets warm.I have changed the throttle body and spark plugs but it is still the same.I have got a friend to put it on a diagnostic machine as the engine management light is displayed and it is pointing to an oxygen sensor on bank 1.I personally don't think it is this as it shouldn't lose power and if i'm being honest then if you go for a long run then the issue does resolve itself until the engine goes cold again.Is there any known faults with fuel pumps or injector rails on these micras and could I just change the injectors without programming them back to the car?Any help would be much appreciated.
If it is mis firing then have you checked the coil pack?Unburnt fuel passing through your exhaust may affect your exhaust sensors,there again to decide your sensor is ok when it flags up as a fault is burying your head in the sand,with modern motors, never write anything off and take anything for granted, the days of setting points are well and truly over.
