I didn't get far off the ferry
Halfway up the M20 the misfire got worse, and quickly got too bad to stay on the motorway. The A20 has no hard shoulders at all, so I've ended up in Sidcup. It'll drive around town, occassionally cutting out, but it's too sudden a cut for motorway now.
I've tried wiggling wires and cleaning the AFM again, but no joy.
The odd ticking relay noise is now on 2nd gear as well as first, even in neutral a bit.
I await the 'very nice man's arrival now
