2007 NC idle dips

Hi all,

Anyone have any info on rough idle during warm up?

Only occurs if you come to a complete stop after a short drive before the motor has fully warmed up. The RPM will drop to around 5-600.

Any ideas?

Thanks!

How many km on it?
When were the plugs changed?
When was the air filter changed?
What fuel (RON) is used?
Manual or auto?
Checked the leads to the coils? These can crack within the insulation and may need "splinting". Check the tech pages or search this forum for more info on this.
