Hi Guy and Girls, I am new to the Mini Cooper S world.

I have found lots of threads to my problem, and wanted to ask if there is something else to try.
Here is my problem. The car seems to hesitate on acceleration, from low revs, but still pulls strong. It feels like it is missing.
I have had it code read and there is nothing showing, the engine light does not come on.
I have replaced the spark plugs HT leads and coil pack.
I have also changed the Fuel filter.
I thought I found the problem yesterday, when I removed the inter cooler, and found that the injector wiring had been rubbing, and found that the wiring had almost snapped, I soldered it back together, and went for a test drive.
To my surprise there was no change, still missing.

Any help would be great.
