Rough idle D4
Hi
Anyone had problems with the idle occasionally starting to get rough and the whole car shivers? As if some of the cylinders lay off..? At normal driving the car is fine.
I hooked up the iidtool and as far as i can see everything is normal, no faults or nothing. The only thing i can see is that the idle RPM goes from 740-650..
This seems to happen only with warm engine.
Short video of the event...

My Jaguar used to idle roughly on occasion.
Whole car used to shudder.
It would also hesitate when pulling away.
Jag could find nothing when under warranty.
I though I would clean the MAF sensors.
Found one to have contamination of some kind, like small bits of grit that you couldn't remove.
Changed both sensors and car now no longer hesitates and splutters when pulling away and the rough idle has never returned.

Fault codes and live sensor data is required as there are a number of things that could cause this.
