    Hi,

    Prepping the Clio for Spa later this month. I've noticed on Cold Startup the engine has a kinda diesel sounding knock which seems to be near the top of the engine. When the engine is up to temp it's gone and instead, you can hear the injectors ticking.

    Is this likely to be piston slap? Sounds far too deep to be lifters sticking.

    Safe on track?

    Hi, does the car missfire around 2,5-3k range?
    Mine did before and it was coil acting up.
