nope they always run extremely lively when they are lean........hence you always here.....it was going quicker than its ever gone, then it melted
also you never said in your first post it was when you throttled off ???
Probs are backfiring from exhaust as tho its rich, and a rattle under load and accelrating
to be fair i would go get it set up properly i.e cam ignition, fuelling etc
i spent a fortnight under and over my S1, asked hundreds of questions it was only through perceverence that i found a small hairline crack in the underside of my metering unit......however i will still get the on boost fuelling checked on it... proffesionally
