K12 1.2 Stalling and lumpy idle


Just brought the car last week, problem Ive been having is a lumpy idle and stalling when pulling up to lights/junctions.

For example if i start the car up in the driveway, the engine runs smoothly when 1st started , it idles at just over 1000 rmp. After about 30 sec the revs drop a little and the idle becomes erratic with the revs fluctuating between 500 — 800 rpm. its almost as if the engines about to stall and it then revs itself up (anti-stall feature ?) to about 800 rpm for a few seconds and the cycle continues. Some times while idling in the driveway the engine will cut out.

The stalling happens when pulling up at junctions or traffic lights, when the clutch is pressed and held in the majority of times the engine will cut out.

Anyone else had experience of this sort of problem?

Model: 1.2 S
Year : June 2005

(BTW — Could any one tell me if 2005 cars suffer from the stretched timing chain issue?)

  • What I’ve done so far.

    Ive checked the spark plugs — all seem to be in good nick (compared them to this Spark plug condition)

    Removed and cleaned the throttle body — was not too dirty to start with

    Checked the DTC’s — 2 found —

    Cleared the code and went for a short drive — Checked the DTC’s and P0011 has returned
    However car runs better than before — idle is stick a little lumpy — comes and goes — does not stall as much as before, but there must still be an underlying problem

    Ive found some info here about code P0011 helpforcars.net

    Would appreciate any advise on which one of the possible cause should be investigate 1st.

  • i,m not sure QB, but you engine may well have been built in late 04 eh
    here,s a quote from a nissan mech

    The timing chain will stretch prematurely due to, apparently, irregular servicing and using the incorrect oil. Personally, I think this is a complete sack of ####e but hey ho. I say this as the cam and crank sensors were known to be faulty and were recalled on 03 models onwards to apparently prevent this happening as well as the chain being a different part no.

    It’s an issue more on the 1.5 than the 1.8 and also effects the newer shape micra’s. You’ll be going along and pull away from a junction and notice irregular acceleration with it pulling lightly then not pulling at all then pulling quite heavily. In my experience, it took a week of this before the engine warning light came on. It’s been knwon to happen at as little miles as 40k.

    It’s interesting to note the part that nissan will replace the chain with is a different number (from the 03 onwards engines) to the original, although they will not admit it’s a problem.
