Engine issue, can anyone help?

Depends, does it just do this when it's cold? My thinking with the injectors is poor/uneven combustion when cold, ambient heat being enough to fix the problem once warm. If it's only on 84k though, would have thought the injectors would be alright...

Temp sensor is the other possible solution, but when i've seen threads on this before no-one posts the solution.

Literally first thing in the morning when she has been sat all night is it. Or longer than 4-5+ hours.
Temperature sensor would be an ideal place to start then as they're only about £15 new. Unlike injectors...

Shame about lack of solution, I'll be sure to post the result when/if it ever gets solved.
