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 :th_scratchhead:
 


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.
 
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!
