    Had a diagnostic testing done after my check engine light had came on and the test indicated that the 3rd cylinder is misfiring. This has been causing my car to jerk or lose horsepowers while I'm driving and as I start my vehicle.

    Car stalls. Then restarts after few minutes. Tack goes to 0. And doesn't work. Then on next startup works again. Engine sputtered while idling and engine light came on
