How does cold weather affect a car engine?
Hello There, As a general rule, car engines do not like cold weather and do not do operate as well in cold weather.

Can a bad coolant temperature sensor keep the car running?
Your symptoms are a dead ringer for a bad engine coolant temperature sensor (ECT). The computer is calculating an air/fuel mixture that is too lean. That’s why pumping the gas pedal keeps your engine running. You can have a bad sensor even without a “check engine” light or trouble code.
