    Hi all,

    I bought a 1986 Audi 100CS Quattro last week and it has been running 
    well so far, except for a few problems.

    When it is cold it won't idle at all, I have to hold my foot on the 
    accelerator for the first couple of minutes. It is also hard to start, 
    it takes quite a bit of cranking before it fires, on my other Audi it 
    starts on the first turn of the engine.

    Also, the other day, while I was driving down the motorway, it got hot 
    and started to knock, but hasn't done it since so I am not sure what 
    caused it.

    I had a look around in the engine compartment and fixed the breather 
    hose which was all rotted out. All of the other hoses seem fine.

    How do I check the mixture on this engine? My 90 has a plug that I can 
    use to check the duty cycle for the ISV, but I can't find a plug on 
    this engine. Do I just use a fuel air meter? I will have to also check 
    the timing at the same time and change the plugs and air filter as 
    well.

    I am a bit concerned about the engine knock- anyone have any ideas what 
    would cause it? The power dropped right off at the same time.

    TIA,
    Ben Doughney
