K11 lumpy idle

I have a 2000 1.0 s on an x plate , runs sweet except for the idle is slightly lumpy and a little slow sounding .

Is this the common throttle body problem as I've had on my previous earlier model k11's ?

Just need to know weather this is the start of the throttle body issue and I can nip it in the bud with a fix before I end up needing to replace the whole unit

I've seen the solder fix video but I don't think this applies to my model

Any help would be greatly appreciated

Many thanks
