Why does car buck when starting cold?
A car may buck when starting cold due to several factors, including fuel delivery issues, improper air-fuel mixture, or ignition system problems. Cold temperatures can cause the engine's oil to thicken, leading to increased resistance and strain on components. Additionally, if the engine control unit (ECU) is not correctly adjusting for colder conditions, it may result in misfires or rough idling. Regular maintenance, including checking spark plugs and fuel injectors, can help mitigate this issue.
