Hi all,
I noticed a funny idle a couple of years ago, and just the last few day I have noticed it again.
Idling at a set of lights and the rpm increases slightly and get a bit of a surge like you get when the aircon cycles but not as large.
I checked it in the drive way rpm increases from 650 to 700.
It is also accompanied by a change in idle sound, sounds almost metallic.
I also double checked if the voltage fluctuates during, which it doesn't, thought maybe the alternator is loading the engine. It only last for around 20-30 seconds then goes back to normal idle.
Will also add I am using the resistor mod for the EGR in case it is related.
Any ideas to what's going on?
