acceleration and idle issues?

[cjswhufc]

My micra will sometimes jutter or not respond to acceleration it will also cut out when slowing down and when idle will be erratic or cut out

attempts to fix:

replaced air filter
replaced fuel filter
replaced afm
replaced throttle body (bosch version)

any ideas on what else it could be?

Had the exact same problem, try unplugging the lambda sensor, if it gets better with it unplugged then replace it.

MAF sensor? Seems to be a recurring issue on K11s, and the problems you describe certainly seem to match

Thanks for the replys
I had already replaced the MAF
tried unplugging the lambada but no luck still not running very well.
any other ideas ????

the idle control valve appears to be on the back of the bosch ones eh http://www.google.com/imgres?imgurl...bm=isch&prmd=ivnsfd&ei=yJEtTrmtM87O-Qbvu_zsDQ
or maybe a coolant temp sensor fault ?
