200 Cold Start Valve / ECU issues

Diolch,
I assume from that, that the ECU won't get confused if
i disconnect the
wire.
Well if it's not working now, then i suppose that in
reality it's
already 'disconnected'

I pulled the ECU codes the other day and got 4444, so
that means that
'there are things that the ECU doesn't know that it
doesn't know!'

FYI the family is from Beaufort / Six Bells, although
I grew up across
the frontier near Hereford.
Arrived over here last summer.

Righto then
i'm off home for the afternoon to try and sort the TQA
before our foray
south across the border this evening.
