Folks, can anybody that's recently changed there spark plugs either by dealer / garage/themselves /etc give me feedback on their idle speed.
Reason I ask is I did a walnut clean at work and changed plugs/coils at the same time.On startup the idle is a bit lumpy so rechecked everything I had done but all was ok.Suspected fouled injectors so again changed them but still the same.
Adaptions reset and road test and is better but still noticeable.
The issue being normal idle was about 650rpm and what happens now is it does sit there on startup but splutters a bit then rises to 800rpm at the DME's request.
There's a lot on the USA forum about this but wanted to hear from more local members.

Thanks
