| For info - mine was degraded vac pipes, I put a whole new vacuum harness on, although I’m sure you could have just fixed the dodgy bit. Looks like an oil leak in the past caused it. |

Hard to say there was so much mess oily residue around/in the plenum anyway. I thought there might be some soot but minimal.
I’ll clean all the sensors tomorrow when the hoses come, put it back to ... |

| I'm leaning towards it being one or more of the rubber hoses running into the donut. It's the most common fault on these 4.4 TDV8's. Had the same problem as you have encountered, FF was fine at normal ... |
