Engine idle 'lope'

[gaz9]

Hi all

Wondering if anyone else has experienced a very random engine idle 'lope'? Every now and then (I have only ever noticed it when in Park) the idle speed will drop down to approx 500rpm for 3-4 secs then recover and return to normal idle speed. When this 'lope' happens it does not 'miss'.

Any thoughts much appreciated.

Cheers
G

I,ve not heard of this in an XJ.Does it ever affect normal driving?

Dirty throttle body? Mine did a similar thing a while ago & the TB was filthy. A good clean fixed it.
