• I've had a problem with my new-ish car.

    I drove from London to Oxford on Christmas Eve, and it was absolutely fine. Stopped in Oxford for 10 minutes or so, and when I started it up again, there was a "Check injection" message on the trip computer, and the engine sounded like it wasn't firing properly - rough idle, and less powerful than usual. Since then I've had to use it on the motorway and it's really underpowered - it won't really go above 60mph on hills, and barely made it up the Stokenchurch Gap.

    Any speculation for what it's likely to be, or recommendations for a garage in East London that could take a look at it? (Mk2 Megane)

  • Got an OBD2 reader? I have one and can lend it to you. ah see you have bought one.

    See if there is a code and then clear it. See if it comes back.

    Before changing anything, confirm that everything with a fault code is connected properly, and contacts are all clean.
