I have a Ctek battery sense fitted, it was that which said 15% capacity, voltage was 12.3V but it was quite cold. The car started ok and when running voltage was measured at 14.1v, pretty normal for my car.

The car did run better with the MAF disconnected and with it circuit my fuel trim and plugs are showing it is running rich, so it definitely points to the MAF.

I am going to take it as soon as my 5 point T20 arrives, give it a clean if it needs it and unless it is as good connected as disconnected then I will order a new one. I should know pretty quickly now what I know what to look for.

Thanks for all the help.
