I was hoping someone might have experienced this before. I've done a search and looked at a few similar faults but I still dont know. I would have thought it was the coil packs myself. As I accelerate and the engine reaches 3000 rpm it splutters like crazy! However if I allow the revs to build really slowly there is no spluttering. Its so bad that there is no power there and is very 'jerky'. I've recently fitted some NGK platinum plugs so I dont imagine it would be them. I've also had the coil packs off for a look but on removal of the rubber sleeve, the contacts look spotless. Hoping its not going to be too expensive. Any info would be great, thanks.
