Noticed this when my phone holder started vibrating on tick over, when the engine is hot and just idling you can sometimes feel a very slight 'miss' or bump in the engine, should I clean MAF? Revs is a static 850-900 hot

There's a comprehensive guide on investigating/fixing engine running issues set as a sticky thread in the D40 Tech Assist section. It can be found here; How to investigate and fix engine running issues

I'd suggest you have a good read through this first.

Idle at 850-900 it should be 750rpm

Thought I should reply back to the kind replies, hmm should I admit this!? Even though the air filter is just one year old ( hence why I dismissed it as being a root cause) the thing looked like its been down a coal mine, swapped out and lumpy tickover gone
