Thread: Getting seriously banana now....

My D1 suffered from HT leads breaking down; I replaced three sets over about 60 00km before replacing them with Gasmaster leads and it hasn't played-up since then (70 00km) along with the Iridium sparking plugs that I fitted.

Now I don't know if these leads will be suitable for a D2 (Justin will know) but I highly recommend them,

Cheers Charlie

Leads are a bitch to change,, (oh yes they are!!)
Buy quality and do it right the first time!!

2 seconds to check a plug,,

I bought NGK Platinums for mine,,
I would strongly recommend using ONLY NGK plugs.



I HOPE its not a coil pack,,
for your sake---

It may be an intake vacuum leak...

Yes, it is a little rough at idle too....

Hi Kieren.

From your description of what you saw and heard under the bonnet when you checked for arcing between leads at night, and as both Justin and Dave have already said, it definitely sounds like leads to me. I'd be going out and getting a set of the recommended leads, and replacing them straight away.

Would also probably pay to check that you are runnning the recommended spark plugs, as I have found before that running incorrect plugs, while maybe not having any immediate detrimental effect on the engine performance, may contribute to early failure of the leads.

Uh, I do not know what ACTUAL effect it has , but on Motronic engines you are only supposed to use OE type plugs, because the Motronic measures the flux of each plug as it is fired and detects misfires by the voltage feedback. So just be careful on plugs and leads.

It also adjust the injection duration based on this info, and "balances" the cylinders by differing the injection duration.. The late 4.0 and 4.6 engines are even not dynamically balanced to the same smaller tolerance than the earlier engines as this cylinder balancing is supposed to achieve the same effect.

BTW the Motronic has an infinite IAC, which is EXACTLY the same as the IAC on my BMW M3, so I have a spare for my M3.
