    hi guys. passed my test yesterday, first time out in the car
    i noticed that when it gets warm its starts to misfire very badly.

    Hi Jack,

    Congratulations on passing your test.

    Misfires can be difficult to narrow down so I can really on give you general tips. Misfires are caused by:

    1) Electrical issues
    2) Fuel/Air supply issues
    3) Compression issues

    Given that things expand with heat check around the inlet manifold for leaks when the engine is running.

    Do you get a flashing engine warning light when the misfire happens?

    Mine did this only when hot then would die & not start until cold solution was a 2nd hand coil pack.

    If it only misfires when warm then it would more than likely be coil pack as said above, classic pug/citroen problem
