Why does my car stutter in the cold?
Beyond the MAF sensor, in most cases, an engine that stumbles when it's cold is caused by one of three different components: clogged fuel injectors, a dirty throttle body, or an EGR valve that is damaged or also dirty and needs to be cleaned.
Why is it bad to drive when engine is cold?
When your car engine is cold, the fuel injectors send more fuel through the system. As the engine warms, it needs less fuel to run efficiently. So the longer you let a cold engine idle, the more fuel you waste and the more you increase the chance of fuel residue build up.
