Am after some helpful advice on my friends Micra engine .
It's an S plate 1.0 ( I think ) . When it's idling ,say for 10 seconds , the revs go significantly higher, stays like that for 10 secs , then drops back down to normal idle. Know this sounds petty but she says even on the motorway the car will suddenly pick up speed itself + she feels its almost out of control !

Any help is much appreciated .

She needs to take it to a Nissan garage to check for fault codes. Probably a dodgy sensor somewhere.

Thanks jlanng .

Anyone else narrow it down any .. not relly near any Nissan dealers.. Are they trustable !?!!?

Tell her that the pedal on the right will increase the revs when pushed

On a serious note, idle control valve?

Petrol, match??
Sticking idle valve or cold start system

Sticky throttle cable?

Has it got Air con and is it switched on ? The compressor can increase revs at idle and on a 1l engine you can get strange power changes as the compressor switched on and off.

Just another angle that is probably b0llocks

Have'nt Nissan just recalled thousands of cars due to a potential ECU fault. Might be worth giving a Nissan dealer a ring to see if her Micra is one of those affected.

Sounds like a faulty idle control valve to me.

Shane, AFAIK the recall is on the 2 litre engines fitted in Primeras, Almeras & MPVs

PS Don't knock that shape micra, a mate of mine who used to be the gofer at our local dealership had a 1 litre micra that went like stink, although, that might have been something to do with him being a nutter behind a steering wheel though
