Engine stalling

Hi all,

I run a 2003 micra which has been a good runner and
apart from a lambda sensor change a couple of years ago,
no problems. Last week though it started to cut out when
coming to a halt. Upon advice I was told to spray some
carb cleaner onto the throttle plates and give them a
good clean. Which I did.

I was also told to clean up the idle/air flow control
valve. Well, on the “how to...” vids it always shows the
idle valve as a separate unit, but I can’t see it.
Is it built in to the main throttle unit in the top box.
I notice this unit is riveted together, if so any tips on
how to repair it or get in there and de-gunk it?

I’m not to bad on the older engines but the new ones with
ECM’s and....wow!

Thanks for the come back flash22

Yes, I had the orange Malfunction "engine" symbol flash up. After  cleaning out the throttle plates it has now stays on permanantly.

When starting from cold and the revs are high all seems to be well but as soon as the choke goes off - it struggles for a few seconds then shuts down.

 

P1171 is todo with the air intake system on the micra

 

camshaft sensor will cause intermitant running or non starting and is a common fault on the micra

either get a ntk sensor or one from nissan,cheap sensors can and do cause problems, evap and the air intake problem may be caused by the cam sensor fault (over/under fueling)

fit a new sensor and clear the faults

UPDATE:

With replacement cam shaft sensor fitted - all seems to be
back to normal.
