Q: missfiring cylinder

asked by on

i have a cylinder misfiring and i dont know which cylinder but know it is misfiring for sure any thought?

My car has 106000 miles.
My car has an automatic transmission.

It is possible the misfire is identified in a readout of Diagnostic Trouble Codes. If it is not intermittent, a diagnostic scope would quickly identify the cylinder. Could be a simple issue such as a spark plug wire defect or plug defect. Such are not unusual faults. YourMechanic could diagnosis this misfiring issue and repair the issue for you in a mobile visit to your home or office.
