Runs fine when stone cold, starts to run rough as it heats up, cuts out at junctions, restarts fine, slightly uneven idle until fully warm, once fully warm runs fine apart from a slight stumble when climbing a long hill.
Pulls fine when fully warm, Turbo spools up ok, EML never on (it's working though)
It's a strange one.
Does it have a coil pack? If so check the plug that goes to the pack. I was working on a C4 which would start then cut out - owner had spent zillions on everything except the one weak point. I unplugged it and showed him the green powder in place of what should have been shiny copper. Cleaned the plug and it was fine after that.
Has a coil pack LGF, pretty sure if it was the feed to that problem would be there all the time, this is definitely relative to ambient temperature, started and ran fine thismorning but it was 18 degrees, was running terrible a couple of weeks ago when it was 2 degrees.

Clue; there's more than one water temp sensor... In fact, there were three of the bloody things, and I changed the wrong one.
I know, three at the back of the cylinder head, green, blue and brown, was lead to believe the green is for the ECU, the brown and blue are for the radiator fans and the temp guage on the dash.
