got a 2001 leon 20vt and its not running right under high revs , was ok till a colil pack went last saturday changed the pack and the other oe one so that they were all new also changed the plugs for new platinum ones.also noticed that there were a lot of split wires on the connections plugs for the coil packs which i re insulated (this did make a small improvment ) tried changing the packs around with the spare one i have but still the same . its ok if i accelarate gradually but if i floor it ,it splutters then massive boost and engine managment light dont know what else to try
