Honestly, it was to clean the TB (which I did with switch ON and brick on the DBW pedal); but now I want to spray CRC or Seafoam intake valve cleaner into the TB with engine running, and that's hard to do. Or, if I can fit spray straw in (without pinching it) and attach airbox/intake hose while I empty the can, I suppose I could do that.
If anybody knows of an accessible vac hose, let me know. As far as I can tell, brake booster vac line is waaaay around back. Hard to get at like rear plugs, everything else on this engine.
