Im getting to the stages where I’m going to start pulling my hair out about this misfire.
From the top.
I had a lean code, lean on both banks. Found some hoses off to the pcv so reconnected, believe the fault was sorted.
Next up I got a bad misfire on number 7, first off I swapped out no.7 coil for no.1. The issue remained with no.7
I then replaced the all the plugs, I purchased these a while back but never got round to fitting them. All the plugs had signs of the engine running lean except no.7 which was black (rich).
I used a NOID light and confirm no.7 injector signal is good.
Also checked the spark through the coil with an external ground. Which was good.
I’ve looked on youtube and the sound it makes is much like the popped plug videos (striped thread). The plug seems tight in the thread, how can I prove or otherwise if this is the case?
