Խուսափեք վարելուց — այս անսարքությունը կարող է վտանգավոր լինել կամ ավելի մեծ վնաս հասցնել։ Անմիջապես ստուգել տվեք։

Inspect and replace the spark plug and ignition coil for cylinder 4 first, as these are the most likely causes. If the misfire persists or the light flashes, reduce driving and have a professional test fuel injection and compression to avoid catalytic converter damage.
