Hello am looking for some advice please, on one occasion my mk2 gti 8v k-jet started misfiring randomly for a few minutes then cleared.
The only obvious thing I can find is the sparkplug leads don't seem to fit snuggly with abit of movement when wiggled side to side.
As am running magnecor leads I don't want to rush out and replace them without advice first, as they aren't cheap.
Should I just buy new leads and stop being a tight arse or book it into a garage?
I really hate the thought of breaking down especially with our little lad in the noisy old car.
I’ve heard some negative reports about the magnecor leads. No personal experience of them though. You could just buy cheap leads and see if it solves the problem. I got some from ecp that I don’t think were expensive and had no issues from them for years. Best isn’t always most expensive. Just food for thought.

I think you're right I'll think about some other leads other than magnacore, I checked them again they just don't feel a secure fit on the sparkplugs.
Usually the connectors for the spark plugs look like this.

They can sometimes open out and stop contacting the plugs properly.
Sometimes all it takes is squeezing them (carefully) with a pair of pliers.
I shall take a closer look thank you.
No worries.
Before you go attacking anything, I'd recommend you take a plug out the car (or use a spare, if you have one) and test each lead out of the engine. That way you can get a good idea of how hard the plug leads are holding on.

Great idea I get my clumsy fat fingers to work the weekend, the daily has new ceramic coated exhaust tips to fit also.

Just checked my magnacore leads are not as your picture Monkey, the connection is circular.
Unfortunately pliers are not going to work they probably need replacing.
Did you take the plugs out of the engine and test the fitment on the leads?

No not as yet the magnacore leads are over 10 year old so there isn't any surprise if they need replacing.
Thanks monkey.
