- Ignition miss-fire
- Have been experiencing some ignition miss-fire recently, although the spark plugs were only a few
- thousand miles and I was confident that they would be ok, I took the opportunity to replace them
- anyway since the charge cooler has to be lifted clear to change the spark plug leads.
These are the old spark plugs.
- The leads were sourced from Nebo, they sell 2 types of lead, 1 kind is about £50 which
- are same quality as senator/gsi leads and carbon core, they also make a more expensive copper core lead
- with correct beru plug cap ends which are a perfect match to OE leads, these cost about £101.00 +vat.

- Unfortunately I have just heard that Nebo's supplier for red leads have gone out of business, Nebo
- can now only offer black copper core leads.
They are numbered both ends which is useful too!
- The beru plug caps are marked with a 1k/ohm, I measured all the leads and found them all to be 1.03k/ohm
- I then measured the old leads and found:-
1= 7.96kohm 790mm
2= 7.34kohm 650mm
3= 8.98kohm 790mm
4= 10.46kohm 930mm
5= 10.56kohm 930mm
6= 12.78kohm 1130mm
- I know bugger all about electronics, but I'm guessing that the lower resistance copper cored Nebo leads
- should be better ? It might be the old leads are within tolerance for the type they are, one thing that could
- have been contributing was that when I was pulling the caps off the coils, one of them came off surprisingly
- easily.......looking in the cap ends, some of the round metal clips were oval, as if they had been squashed
- with pliers to get more grip, who knows...the new ones are on now.
- The acid test is a drive, so a blast around the block, and not one miss-fire !! excellent, I never tried the radio
- so lets hope the noise suppression works.
