P050DCold Start Rough Idle

⚙️ Powertrain (Motor y Transmisión)
Moderada

The ECU detects rough idle behaviour during the cold-start phase only. Once the engine has warmed up the issue disappears. Typically caused by injector deposits, low compression on one cylinder when cold, or sticky valve guides.
