Thought ok, that's not meant to look like this. Definitely a worth while investigation as no doubt the partially block solenoid ports will be having an adverse effect on not only engine smooth running, efficiency but performance also.
Cleaned and tested both solenoids, working at least from what I can gather.
Clean up pictures, note also some sealant inside bank 1 solenoid too ffs. As you can imagine the engine feels noticeably better for it and the idle is now bang on!!!! Not driven it a great deal, but the light throttle matter in thr higher gears is nowhere to be seen either - result.
