How to clean soleniod :

The gold cylinder shaped thing is the boost solenoid. There are three pipes connected to it, one on the top that just pushes on, and two towards the bottom held on by clips. Remove all three pipes, squirt aerosol type brake cleaner into the pipes and into the solenoid itself, reconnect the pipes and go for a blast before the cleaner evaporates.
