It's random, sometimes it's fine sometimes it's a pig
Started happening today after a 12 mile journey
It's like a misfire
 
Sorry, it's not just third, I only tend to rev higher from third onwards
It's over 3000rpm ish
I unplugged the lead to the maf, it made no difference, meaning that's not the culprit
It's booked into garage tomorrow so hopefully they will have an idea

Au contraire mon brave. If there's no difference it means the MAF isn't working !!!
 
Il see what the man at garage says
Il check for oil when I'm on lunch tomo, shall I pull the ecu out and unplug the earth from battery?
Whats the best stuff to get rid? I got turps or MEK at work that should do it
I could clean the maf couldn't I with electrical cleaner but I have none ATM

I find the best stuff for cleaning the ECU plugs and sockets is aerosol brake and clutch cleaner.

Just an update
Air flow meter was swapped, no change. Ecu terminals fine
Mechanic said to change the fuel pump as the diagnostic tool cannot pick up lack of pressure on it, as its an in tank type
