Q: misfires on all 6 cylinders...doesnt do it all the time

asked by on

ran a scanner on it and it gave 2 codes...first one said ignition coil A primary/secondary circuit second code was AF/02 sensor data

My car has 210000 miles.
My car has an automatic transmission.

The most likely cause of this issue would be a wiring issue to the ignition coils. Since all cylinders have a separate ignition coil, one of the few things that can cause the engine to misfire on all cylinders would be the wiring harness that connects the ignition coils to the pcm. I would recommend having this wiring harness tested by a qualified professional.
