I had the same sort of problem when I floored it in 2nd and 3rd and chased it round the engine. I took it to a specialist and found it was the coil pack. They degrade in the inside so it's not visible. I got a 2nd hand one from eBay and now the problem has gone! You can get then from breakers on here for about £25 if its the one that sits on top of the engine.
