think you;ll find there's 2 diff types depending on the type of 'posts' that the HT leads connect to Lee....
if you have a scrappie near you just wander it down there and you'll pick one up for a tenner.

Tenner??? Isn’t a coil pack pocket size?

I thought pocket size items were legally free from a scrappy - or don’t they operate like that anymore?

Thanks mark.
Actually the problem i have is that pot 4 furthest from driver is giving me a black plug and pops a little from the throttle body trumpet and my idle at cold is hurrendous almost stalling until it warms up then its fine.
First thought was plugs sonive changed them but still there so im thinking work back....leads, pack tgen the 80 quid injector and if its still there then il have to do a pot pressure test.
Be nice if you coukd just change the leads around to rule out a bad lead but they fit perfectly so cant do that.

Is there a way of testing the pack and leads with a multi meter.
Although all other leads click back onto the plug pot 4 just seems to slide over so im wornderingbif it could be that.

Lee, first port of call is a compression test. Pot No. 1 (the one closest to the nose of the car) is notorious for running cold in a RWD installation as it’s closest to the fan and air flow and Zetec’s don't like running cold. I ran a “diffuser” from the back of the rad and in front of the engine. It deflected air up and out of the air vent on top of the nose cone, for specifically that reason.

Hope that helps?

If only one plug black it won't be the coil pack. The coil pack only has two coils (wasted spark, two plugs share each coil) hence the three connections (1 common and two coils).

Re reading sounds like your throttle bodies may need balancing.

Thanks dave.
Could you explain the wasted spark to me a bit more mate.
If pot 1 is black should pot 3 be black too if it was the coil pack.?

I think that's the case, basically when #1 is on a 'squeeze' stroke, #3 is on a blow stroke. At the top of the stroke both get a spark, but obv it only causes a bang in #1, and the next cycle the situation is reversed, again both get a spark, from the same coil but it only goes bang in #3. if the coil was the problem then it will affect #1 and #3 or #2 and #4. If it was mean I'd change your leads, Magnecour seem quite good. Was interested to read the post about #1 being colder due to it's position, I guess the affect would be more pronounced in colder weather?
Yes I've been drinking, what of it!!
