    Have you tryed some fuel additive/cleaner ?
    On the first restart it appeared as if the problem had been solved but alas, it appeared again within minutes and thereafter within about 30 seconds of every restart.

    Have not tried any fuel conditioner as I have been warned off these?

    Cheers

    From memory it was a cheap fix.

    By the way I gave your hand held to Simon.

    Chuck,

    Any idea where the turbo relief valve is situated? Trying to look through Rave at the moment but can't pinpoint it.

    Cheers,

    Thanks Angus. Started it up this morning and it ran fine. Am going to fill up and see if driving it brings back the symptoms or if I can detect any bubbles in the fuel tank as per Andrew's suggestion.

    Cheers,

    Franz

    Hmm, this is why I think it might be a sticking injector.
    You need to get the nanocom on it and find out.
    Might run a poll in the disco section on fuel conditioner. And see what comes of it.

    OK, here's where I'm at:

    1) Injector harness plug ECU end - no problems here.
    2) Injector harness plug Rocker cover - no problem here.
    3) Injector harness under rocker cover - cleaned that - seems to be a fair bit of oils around but not really sure what it should look like.

    Started again today and it ran fine although I did not take it for a run.

    There are small pools of oil in the troughs under the rocker cover (see pic) - is this normal?

    Cheers,

    Franz

    How do I determine if it's faulty - Nanocom?

    Cheers,

    I have now checked the ecu with a nanocom and found two error codes 27-05 and 31-05 which relate to injector #5. Could these faults have been caused by oil in the loom? The codes cleared OK and have not appeared again to date.

    Any clues?

    Cheers,

    Franz
