To be honest SHIT building up speed is useless iv even had to drop it into 4th on the motorway cos 5th loses power, it's had new coil pack, leads and plugs, there is abit of oil around the drivers side driveshaft where it goes into the gearbox, could it be the gearbox is low on oil??? Im driving from Leeds to Manchester in an hour to pick up a bumper, it's got half a tank in which should be more than enough but I think I'll be coming back empty it's that bad
