    Coil pack problems????????

    My car has started to miss fire under load.

    At first I thought it was the AFM but I tried another one (A new one) and it was still the same.

    Looking at the coil pack the end closest to the battery looks like it has carbon deposits on it so could be arcing.

    Any ideas what else it could be if it isnt the coilpack.

    Apart from the obvious dodgy sparkplug, can't think of anything else that would cause it. Someone had a coil pack for sale on eBay a while back and it went unsold. I could probably dig out the contact for it if you want to see if they still have it.

    Edit - I dug out the contact (as I enquired about it at the time), email is michelle@stvconnect.co.uk

    Thanks Mike but I brought a new one and fitted it tonight.

    The good news is that it was the coil pack and the car runs sweet now.

    Thanks for sorting the guys number out.

    I'm interested to know what the coil pack looks like?

    Do you have a picture of one so I can check mine out?...

    Thanks Mike.

    Oh that, i didnt realise what it was called.

    My car idles a tiny bit under what it should, and judders a tiny bit - just noticable.

    Ive changed plugs with originals again (unmodded engine)
    and always fill up on optimax. AFM is fine, tried another.

    its a mystery

    The above coil pack is specific to the Z20LET, they usually look very very different to that on other engines.
