I recently bought a K11 1.3LX. Lovely car to drive - can't believe how quick it is, for something so understated.
Anyway... it's had a few problems lately, mainly that if you floored it, it would cut out etc.
I've recently changed the throttle body, and it now runs quite happily... most of the time.
I have noticed that when it is warmed up, sometimes if you give it a foot full, you can feel it slightly hesitate - doesn't judder or anything like that, but it's noticeable.
And then last night, I hadn't gone far, gave it some throttle coming out of a roundabout, and it started to violently 'Kangaroo', and whilst it would still tickover, I had to sit still for a couple of minutes with it ticking over, before it would rev normally... oh, and I could really smell the 'rotten eggs' smell associated with a cat warming up.
I've driven the car this morning, and the problem has mainly only showed up when I've floored it, or I've been travelling at speed down a dual carriageway - once it shows up, even if you slow down, it doesn't go away until you've stopped, and let the car idle for a while.
If pull away at a sensible pace and cruise along at 65ish, it doesn't show at all.
So... is it possible it's yet another throttle body fault (given these appear to be a bit of an achelles heel on the Micra), or would the above be explained by a dodgy temperature sensor (which is another known Micra issue), or is it likely to be something else?
A semi collapsed cat springs to mind, due to the fault only generally showing up when the car has been under load for some time.
TIA
