Question

Intermittent code and problem.

Answer 1

Hi there,

This code is basically for the #3 ignition coil. I suspect it's not consistent because usually with the coils it takes certain circumstances for the problem to occur. What I suggest is swapping #3 with the one next to it, then see if the misfire moves to that cylinder. If it does, then you know the coil is the problem and you can replace it.
