Ok, its nothing special but it is my daily hack so I need help urgently.

It's a mk4 escort 1.3 on a standard Weber carb (with manual choke), when I start it in the morning it runs really badly like its missing or the timing is out. But when it warms up it runs perfect?

I've given it a service and it still happens like clockwork. Someone has suggessted that it may have an electronic cold start valve, but I'm not sure if it has or not. Does anyone know?

I have noticed a sensor type thing connected to the underneath on the inlet manifiold, could this be the problem?

Thanks in advance
