2G Boost leak test

[MasterMatt209]

I'm doing a boost leak test but my system won't hold any pressure at all. Am I supposed to cap something off or soemthing? Idk why it won't hold pressure

Where is the brake booster, injector seals, BOV adjustment, and FPR adjustment located? Also what's does the BISS screw do?

Injector seals are at the bottom of the injectors. At the very bottom where the injectors sit into the intake manifold. Injectors also have o rings on them. It's a pretty simple job to pull the fuel rail and replace them. In fact I just replaced mine about an hour ago because one of mine was out of round. If you do decide to pull the fuel rail pull the injectors off and inspect the filter for rips and dirt. The brake booster line is the line that t's from the master cylinder to blow off valve to waste gate. Fpr stands for FUEL PRESSURE REGULAR. This is located at the end of the fuel rail. It looks like a circle or dome with two lines coming off it. Ones a vacuum line and the other is a fuel line. It Will be on the driver side of the fuel rail. The biss screw basically controls idel and has a few things to do with isc positioning. Good luck hope this helped

You are going to have to do some research yourself so you can get used to looking for solutions to your problem. Then, if you cannot find an answer, post it.

I will tell you if your car is what you have listed in your profile, then you cannot adjust your bypass valve (the car in your profile has a 1g bypass valve), nor can you adjust fuel pressure regulator that you have.

If you are not up to replacing the shaft seals on your tb (which is also where you will find the BISS screw), contact the gentleman in from the website below. He rebuild throttle bodies, and would likely send you a rebuilt one in exchange for your core for a quick turn around. He is very professional and has been around a while.
