Hi
My AGPSS has developed a 'pinking' noise over the last thousand miles or so.  Typical conditions for 'pinking' ie low rpm - high load.  Just wondered if anyone else had suffered the same and knew of the likely cause?

I've eliminated a few things like contaminated fuel (I always use either Vpower or momentum99 and have tried several different petrol stations).  I've also fitted new spark plugs.

Apart from the 'pinking' the car runs fine.  Any ideas would be most welcome. Cheers in advance 

not heard of this before, faulty sensor maybe?

Hi Lloyd
That's what I was thinking, well either that or an ECU fault.  Bit expensive to just guess and change parts, was hoping someone may be able to point me in the right direction. 

I'll probably start with the crank sensor unless someone has a better idea . . . . . .
