Hi guys, here's a quick update.
I took the old Air flow metre off the car (it was pretty f**cked so I guess i needed one either way). Bought a new air flow metre and fitted it. Its made the car sound allot crisper BUT it has not solved my problem if anything its made it even worse, even more laggy and powerless. It pops and bangs like crazy now even sometimes it sounds like the popping is coming from the middle/front of the car.
Back to the drawing board, getting pretty fed up of trying and spending money on the stupid thing!
P. S here's a photo of my car we're
