Testimonial: "Thanks for getting back the year is 1998 MK2 p38 HSE its a distributorless and EFI no carbs. Wondering whether its the coolant sensor or fuel regulator. No egine light is on so not he O2 sensors."

It turned out to be a broken wire on the injector which was causing a bad connection,now running better than before.
The cold was just a coincidence.
Thank you and best regards,Yvonne

Bring your vehicle to an auto parts or battery store. Ask if they could perform a 'Load Check' on your battery. This not only checks the voltage, but also the amps, as if it were under the load of turning your engine.
It takes a few seconds and the results are pass or fail. Fail means it's time for a new battery. Pass means we need to look elsewhere.
Comment back the results.
Hope you find this to be very helpful

I think you're right - it sounds like you're running to RICH (too much fuel / not enough air), but I would think that you'd see the check engine light on.
If you are too rich, there's probably an O2 sensor or other computer issue going on - and if allowed to persist, you'll probably end up with a clogged catalytic converter. As long as the sensor / computer is adjusting your air : fuel ratio, there little you can do to override it. I believe the computer will continue to adjust the mixture to get what it wants to see by the O2 sensor in the exhaust.
Bring it to a mechanic / dealer to get this fixed correctly - before you waste any more fuel or cause additional problems with the cat converter or other parts.
