2000 GT NON-SC Vacuum Diagram anyone?

[JerzNick]

Just like the title says...

I need a diagram for my 3800 NA motor that I dropped into a different car. My ltft's are pegged @ 16.4 so it's either a leak that I can't find, or something is missing

wrong sub forum...

move around the engine with a can of brake cleaner and keep spraying until you hear the engine rev up a few hundred RPM's. WHen you do, thats your leak.

[JerzNick]

Went through 2 large cans of carb cleaner... No rpm change.

[scottgs03]

what did you recently change? LIM gasket? TB gasket? replace injectors? They have the potential to cause vac leaks...

Well, after installing a few new vacuum t's, my ltft's at idle are between 1-2. The instant I go 10% throttle or more, the ltft's shoot to 25 and the car runs line hell...

What I've checked so far:
-Vac leaks... No vac leak.
-Replaced MAF - Same issue
-Replaced both 02 sensors - Same issue
-New AC Delco plugs installed with all new ign wires - Same issue

Any ideas??

This engine is completely stock. All I did was move it from one car to another, no mods at all!

Did you check the check valve at the brake booster?
did you remove the EGR tube and check that?

Did you check the check valve at the brake booster?

There's a check valve there? I take it you mean in the vacuum system somewhere?

[BillBoost37]

the hose that connects to the brake booster. that swivel piece that sits into the hose and booster..it's a check valve.
