Suzuki Sidekick Pressure Regulator 1.6 16v.
This regulator regulates the pressure inside of the Plenum. When this goes back fuel will start to flow into the regulator causing emission failures.
A quick test is to pull the hose off while the motor is running, and if fuel comes out, then it needs to be replaced.
This is a new aftermarket item.

Pulled the vacuum line off and a llitle fuel came out. The hot start caused excessive cranking and idle was off for a while after. The fuel pressure was off and didnt hold after shut dowm.. Installed the new one and it runs better and starts hot quick and idles perfect the idle control works the way it should
