out of no where it revs itself to like 5,000 everytime i start it

[DARKTSI]

ok i finished my 4g63t swap and it started fine and everything but out of no where it revs itself to like 5,000 everytime i start it....i have to push on the throttle cable to lower the revs and turn it off...also my exhaust manifold smokes crazy any ideas why?

sounds like something is pullin ## throttle cable, check the fuel injector area , usually is where it gets stuck because of the wiring, ## mani is probably smokin ### of the oil & grease that always drips when workin on our cars, especially on a swap wich is alot of work.If it keeps smokin then I worry

That is correct... on both things. Check the throttle cable. And the smoke is most likely from some PB blaster/WD-40 that got on there while doing the install.

You shouldn't be able to hear your BOV while idleing. Is that what you mean? Or reving it up or what?

And you should be able to see the smoke coming from off the top of the manifold itself.

Check your biss screw too, and do what you see up above.

the biss screw is located on the throttle body, it's to the left of the hoses on top of the throttle body, should look like a phillips head screw try to adjust it if your still reving high. The smoke should go away it's probably from oil or something when you were removing it possibly put oily hand on it, and remove the tube going from the bov to the intake and rev it up a little and see if your hearing any noise, if not then take the bov off and see if you can open it manually, it might be stuck.

sounds like a vacuum leak check that the pcv valve is connected and the hose in the back of the intake manifold thats feeds vacuum to the brake booster
