Just thought I'd ask a really simple question ...
How much difference should there be with the MAF sensor connected and with it disconnected?
I've been troubled by poor MPG for a while and still can't find any reason. A friend has recently had to replace their MAF sensor on a Bora which made the world of difference to it so I thought I'd try to test mine to see if it works.
Firstly I put a metre on it whilst blowing air on the blade, there was some change in it's output but I've no idea how much there should be.
So I unplugged it to see what would happen and there was no noticeable change at idle. I took it out for a spin and there was definately less life in the engine and the turbo seemed non-existent, which is what I was expecting really. But what supprised me was that there wasn't that much of a drop in performance, it still revved OK although it took longer to get there and there wasn't any obvious smoke or any other indication that the engine was running rich/lean.
How much difference should there be?
How can you test the MAF to see whether it is working/calibrated correctly?
Many thanks
