Hi there,

I have an S2 thats just come out of hibernation after a lengthly 'sort out'!
It was running sweetly this morning, better than ever in fact, I took her for a 30 mile drive along A & M roads taking it nice & easy, after I sat on the exit slip & pulled off, it suddenly started missing really badly, hardly able to pull away, once boost crept in it would run fine & the miss went, I took it real easy as when it was on boost, black smoke was coming from the exhaust.

I got it back home to find some very black spark plugs, I replaced them yet the problem is still there.
I'm hoping it's just an electrical fault somewhere but I'm not sure where to start. I checked the coil wiring & HT leads, coil & lead are no more than a year old.

Any help will be greatly appreciated....

Col
