Hi guys, i am putting an l59 from an 01 or 02 silverado into a 92 300zx. The engine has a triple 12 cam, typhoon intake, and a 102 throttle body. When i start the car, it spikes up to 3-4k rpm, then starts to slow the engine revs, when it gets down to idle rpms, it juat dies. If i feather the throttle, it will stay running.
kinda sounds like a vacuum leak to me, but im not sure. Ill check codes as soon as i get my dongle in the mail

any thoughts? Would the throttle body cause this many problems?

thanks!

Is it tuned for all the changes? That would do it easily if not custom tuned.
