1.6 Essenza c+c

Hi,

I changed the spark plugs on my wife's micra and now the idle won't drop below 1500 rpm. Doesn't seem to be any air leaks and I'm at a loss where to look.

Anyone got any idea's?

Thanks.

are the plugs you put in the same as you taken out? or have you changed them for platnums because i get customers in my shop asking for platnums thinkin it makes it better but insome cases they run worst

i put the denso iridium plugs in my K12 1.0 worked a treat €60 the set, a bit steep though lol
i found though some brands of plugs just dont settle well in certain cars... what brand did u use?

I put in What I took out. NGK.

To get to the plugs you have to take the inlet manifold and throttle body off. I'm pretty sure I put it all back properly but what's happening indicates an air leak.
I can't find it but as I've not got a garage to work in I'm going to leave it until it warms up a bit!
