Running too rich? fouling plugs between hard shifting?

Rob, yeah it was cylinder 6. I'm going to try 'violently' twisting the loom about to see if I can induce the missfire. last time I tried I was being a bit girly about it... so I'll give it another go.

I really knew I should have replaced the injector plugs though. The injectors seriously look just as grott. green corrosion everywhere. I wanted to replace the injectors and their mounting bolts when I had the plenum off, but was advised not to... so the next round of maintenance might be another big job... sigh

 

This......

..........is the place to start.

Well, I can rule out hitting limiter as the cause. Within 10 minutes this morning, it dropped a cylinder under even just moderate load.

I tried to rule out BOVs by standing on boost, lifting and getting back on it, but runs fine ish :/ It still feels like its not getting good spark though. Feels like its only half there and comes in and out a little bit randomly.

Maybe I'll just go hell for leather, new injectors, new connectors, new ptu, new loom
