Based on some of the comments about Shell fuel earlier in this thread, I decided to experiment with different fuel. I ran my tank to almost empty and filled up with Chevron Supreme 91 octane.

All I can say is *WOW*!

Within a day the car was a completely different animal. I can now put my foot to the floor in 2nd or 3rd gear at 2000rpm and I get *no* funny pinging noises whatsoever. It just pulls, smoothly, even up an incline.

I didn't really want to believe this, since I've been putting up with this issue for over 2 years - but even the girlfriend has noticed that the 'funny tinkling noises have gone away'

Anyway - I don't know why this made a difference, but I'm very happy and posting this in case it works for somebody else.
