Just been up to York and back at a total of about 290 miles. The journey up was fine but on the way back the car juddered a few times. No loss of power or any other symptoms. Coolant temp was fine. I had my odb adaptor running at the same time.Once I slowed down a bit to about 55-60 it was fine.

I think I know what the issue is but want some more opinions.

I think its the coil pack as this may explain the rough idle. I am planning on buying one this week with some new HT leads and plugs.

Any other opinions?

Its a 2001 Ghia 1.6
