My Jaguar S type 2000 model is misfiring intermittently, sometimes quite badly.Up to now its run perfectly. Has anyone any idea as to what might be the problem? Thanks

[tonyav]

What engine has it got, and is it petrol or diesel ?.

[chrissa1]

Water in your fuel maybe? This happened at a garage near me.

sounds like a HT lead problem to me sart it up when dark and if yuo can see any sparking on one of the leads it willk need replacing.Failing that it could be a partially blocked fuel jet,this is if it is apetrol engine by the way
Good luck

Spray WD 40 on all the electrics + leads & try.

Possibly the coil pack?

[barney721]

Thanks for your answers re my Jag.The engine is petrol & it starts up fine when cold, no missing. This occurs when heating up & when hot. Platinum plugs were fitted 10 k mls ago in 2010 so shd be ok

Ha Ha that tells me that the head gasket has gone,check for oil in water or water in oil if there is gasket will need replacing.

Is that funny Grumpy?

TWR

I think Grumpy's , Ha Ha , is meant to be 'Ah Ah' as in ' I see '

[Baldric]

TWR, you really need to get out more
ha ha can also be an expression of triumph or understanding, as in;
Haha, now I get it (understand)
which is something you obviously don't do :o(

[GRUMPY]

TWR as Bazille suggests

[chrissa1]

It would have been better written, "Ah Haa." Lol.

I think expert help needed for a Jag,but tony is good.

Thanks your input chaps. will check for oil in the water asap. Any other suggestions? Polite please. Barney721.

Have checked coolant for oilslick but is ok . Car also had oil & filter change . am sure water in old oil wd have been noticed. WD40 has been tried as well but there are no leads to plugs unlike most cars. neither is there a single coil. Each plug has its own coil which complicates matters. One could be breaking down but how to check. Mark mentions the coil pack. Thanks all. Barney721
