did you have this problem before you changed the plugs, filter ect..?

bit of a longshot but it could be that the petrol pump is underperforming, thus at high revs it is not delivering enough petrol to the injectors

hiya on my astra I have electronic ignition no ht leads

what carries the power to the spark plugs?

Toureman

LT wires carry the power to the coils which then generate HT to the plugs.

New filter and oil will not have any effect on making the engine stop misfiring, don't know what the etc is though.

it has one single coil which feeds all 4 plugs. ht leads havent been fitted to 90/95% of cars for a few years as most cars are now electronically controlled
