Great to read that you got everything sorted and I bet it was worth all of the effort when it was up and running.
My Micra isn't too bad. It still takes a couple of turns of the starter motor to fire up the Dci engine but I have gotten used to it now. The clutch is still high but the chatter when I change gear has gone after my last visit to the dealer so not sure what they did but it is fixed for now with the promise of if the clutch does start to slip any time soon then they will sort it FOC.
Took it on a 250-mile drive yesterday and it is still averaging 50mpg so I am going to take the EGR Valve and associated pipe off soon and see if they are all gunked up and then give them a good clean and then try and locate the MAF and give that a clean, just got to find it!
Checked the air filter and it was brand new and clean, quite surprised how it easy it was to get at so no problems there and the oil level was fine, hadn't dropped or anything.
Overall, all ok it's just the MPG on a road trip that's putting me off the car a little as I still feel that I should be getting more miles to the gallon but will see if the things I am looking to do in the next few weeks make a difference. If you can point me in the direction of where the MAF is situated that would be a massive help!
