Q: Cylinders misfiring.

asked by on December 28, 2016

The check engine light is blinking and TCS is on.

Someone did pretest and said the cylinders were misfiring. What causes this?

Thanks

Hello - an engine misfire can be caused by ignition issues (bad spark plugs, plug wires, coils, or ignition module), or by fuel issues (clogged or leaking fuel injectors). I would recommend an engine misfire inspection by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.
