Getting seriously banana now....

The D2 has no dizzy, cap or rotor as it has coil packs, and closed loop fuel injection, bosch Motronic to be precise. It can be plugged in to a Bosch real time engine analyser etc for a second opinion if you need it. I'm going with the plug leads personally, the D2 engines are supposed to have Platinum plugs which are good for at least 80K.
Also, fuel pressure and volume are critical for these engines, and your comment about rotten eggs smell means that the cats are doing their job. It actually sounds like the misfire is spark related as the smell gets worse when a rich mixture is encountered, IE unburnt fuel.

Thanks AussieLandRover!
This is my prob though. There's been lots of "could be this, could be that" issues with the Disco, and when it gets replaced, prob still there! Its an expensive way to find problems!

Since buying the car last June/July, I've spent an f-in fortune on it, had the engine rebuilt under warranty, spent more on top of that, and still no fix!

Really getting on my t!ts now - not you, the Disco! ;)

ditto, I thought the TPS problem was a TD5 or better problem....

Thanks Justin.
I'm going to get onto the phone to DA first thing and find out about these leads, wether they were new or not.
So, looks like I've blown another several hundred dollars on a pair of new CATS when I may not have needed to....:mad:

Cheers for the input,

Take the car out at night. If it is missing at idle stop and pop the bonnet. See if you can see any of the leads "arcing". Make sure it is nice and dark when doing this.

It might just help and it costs nothing to do.
If you are handy with an Ohms meter you can also measure the resistance in the lead as well.

Good luck

Does it have an Idle Air Control valve (IAC) as fitted to the rear of the earlier model plenums, sounds like it to me, Regards Frank.

Just done this, and there does seem to be a very slight blue flash on the passenger side banks (approx 3rd plug from front). Not 100% sure though. Saying that, the missus rev'd the car in the dark, with my head under the bonnet, and there was a very distinctive "clicking" that came from where I thought I saw the blue flashes.

The reason I say not sure, is that when looking directly at the spot, I couldn't see anything, but when my focus was just off, I could see some extremely slight irregular blue flashing.

thats your leads breaking down.

Like Dave says, that is a classic lead breakdown. They don't last long on these vehicles as the heat around them is pretty extreme.
