75 twin spark runs rough when cold

[supervanawesome]

My 75 2.0 tspark seems to be grumpy when started from cold. Will usually cut out unless i keep the revs up for around 30 seconds and will hestitate and loose power for the first few minutes of driving. All new plugs and ignition , no obvious vacume leaks and have cleaned idle control valve. Idles and drives good once warmed up. Has anyone else had this issue?

Check the coolant temperature sensor for the ECU. Make sure it plugged in and that the pins in the plug are actually attached to the wires.

As Duk said, check the temp sensor. It is awkward to get at being buried underneath the no. 4 inlet manifold and above the starter motor but if you remove the AFM and black concertina piece you should be able to get a multimeter onto the pins of the senor where you can check the resistance and cross reference it to a suitable chart (ohms v temp) like found here;

See section 7. I have found a proper chart somewhere but can't remember where.
