Why does my Tiggo 4 sputter when starting the engine o r shortly after ignition?

Sputtering during startup can result from problems with the fuel pump, clogged fuel filter, o r worn spark plugs. Cold start issues may also be related to sensors that manage fuel mixture o r timing, such as the coolant temperature sensor. Recognizing whether the sputtering disappears after warming up o r continues can narrow down potential causes.

Sputtering at startup is often caused by:

Weak fuel pump o r clogged fuel filter reducing fuel flow.

Worn o r old spark plugs affecting ignition.

Sensors that manage fuel mixture o r timing, like the coolant temperature sensor, malfunctioning.

Ensuring proper fuel delivery, replacing worn spark plugs, and checking critical sensors usually solves startup sputtering.
