Hello and

Anyway, no answers, so I will try and help..... The obvious might be fuel, but what about some other things like AC compressor turning on and off?? The idle does change with a load from the AC unit....

If it happens when the engine is cold, that is another thing again, as the sensors readings change as it warms up...

It is probably not a worry, in any case... Heck, be happy it idles, "Sounds of Love"... Ha!
