Bad coil pack

[Whitelaw87]

Hi all, I am assuming that I have a bad coil pack, I have a 53 plate 1.4 petrol megane, while driving today the orange engine light started to flash, it would do this for a while and stop, then start again, and at the same time while driving the car was juddering, kind of spluttering defo not running smoothly, and when idle shakes a lot more. I have looked this up and reckon from other posts that there is a bad coil pack, i also really need to attend uni tomorrow and my cars the only way of getting in, i have looked up on how to check for the bad coil and how to change it, this seems pretty straight forward, the problem is i don't get paid until monday and really need to use the car, would I be ok driving the car on a 30 mile round trip? 15 there and 15 back? The car starts first time and only judders when driving it never stalls, I know running it too long May damage the CAT, how much usage would damage the CAT? but would it be possible to use it for another 30 miles before it gets fixed? Or is this a big no no? Any mechanics verdict will be appreciated, as I stated the car starts and goes it's been juddering though.

Cheers

Kyle
