engine shaking during idle regardless of P / N

Dear All

My LR3 v8 HSE is shaking during idle (P/N), it happens around every 4-6 seconds. I use OBD tools (iCarSoft) but no error registered from engine or transmission (auto gear box).
Millenage: 212000kms
Last time spark plug replaced was at 185000 kms
MAF is cleaned

What could be the issue?

Thanks

Is it just a shake, or are the rpms fluctuating too?

You can feel mine on idle once its warmed up.

Doesn't really shake, more of a slow wobble. 05 V8 HSE Bonatti Grey

rpm is below 1000 rpm, I checked with OBD II its between 600-750 rpms and it's stable not fluctuating

Finally it's throwing engine system fault with OBD II fault code: P304: cylinder 4 misfire

Replace the ignition coil cylinder 4, now it's fine, no more engine shaking
