Thanks for all the advice people!
I was really spun out when all the other scooby drivers around where I live started flashing their lights and waving at me, I thought they were warning me about police or something. Now I know to flash or wave back!
The fuel filler cap has a sticker saying 95 octane only, is that something I should listen to?
I have another question though. The fuse for the secondary air pump has blown, making my engine management light come on, I've read loads of posts about the secondary air pump being a pain and that it's not really needed, but the light on the dash is getting on my nerves. I've looked online and I can't for the life of me find a fuse that looks the same as the one in the fuse box that's blown. Does anyone know where I can get one that'd fit it?
Thanks again everyone!
