I ended up pulling the solenoids apart and cleaning them out with MAF cleaner, followed with some gt-85.
The red one seemed to have a little moisture in it.. could have been the issue? Although not entirely certain.
The mesh part of the filters was completely worn away on both solenoids and the switch. Have put them back in as is for now and planning on ordering some new ones to replace them with.
I also bought an etorx set and took the vacuum hubs off for a little look and couldn't find any evidence of grinding between the hub and spindle.
I wonder if its possible that the issue could be with the front air locker?
Now I just need to go find a cattle grid to drive over and hope this is the end of it.. only time will tell.
