Missfire, could coil pack have failed in under 2 years?

[KS5000]

I have a 2001 tuscan, had a missfire, changed all plugs and worked fine. 3 drives later. missfire again. so guessing plugs are ok. had the leads and coil pack changed less than 2 years ago. could either the leads or coil pack have failed in under 2 years? any advice would be great. dont want to spend £120 on coil pack....

I would change the leads first, but the coil packs aren't great. I managed to get a spare of fleabay, when I had a misfire did the same as you and it looks like it was the coil pack. The leads were buggered as well. Have you checked the leads, have a look at mine!



They were originally fitted to the V6 Vauxhalls and there are 3 derivatives but only one will fit. Did you need the model number?

Is that from a badly sealed plug cover?

[nrick]

Yep

Not such a cheap option, but my misfire turned out to be a cat, which ended up being a dog, replacement installed, sorted

How was the cat diagnosed? any tell tell signes if it is the cat?
