Hi, I have a 2013 Astra J GTC VXR stage 1. For the past few weeks i have been having acceleration issues where if i'm in 4th, 5th, 6th and i put my foot to the floor the car doesn't gain speed. the rev counter just jumps up and down and sounds like i'm revving the engine as if it's on neutral. I've taken the car to Vauxhall and they couldn't find an issue. Any suggestions and solutions would be appreciated.
