Damn car still has the hiccups.

It's not leads - they've been replaced.
I checked the O2 sensor wire and replaced the sensor - in doing so pulled the old coils and fiddled, then put them back in - it seemed to behave for a few days, but the problem is back.
Borrowing a set of coil packs to test if that's the issue would be appreciated, and then I can look to purchase if necessary (from somewhere).
PM me please if you can help.
