For future reference, label everything if you don't have a diagram.

Can you put up a picture to show us what we're dealing with here?

BTW, don't be afraid to use periods for complete sentences.

What manifold was on the car before, a DPFI(DX) or MPFI(Si or HF) manifold? Did it run normally before you installed the new intake manifold?

You could have one problem, or a combination of problems. Start by checking all your vacuum lines for cuts or cracks. Make sure all the vacuum lines are plugged back into their proper places. Make sure all your sensors are plugged back in. Make sure the intake manifold and throttle body were tightened properly.

If you have a failing component it may be hard to tell which one it is. By playing 'process of elimination' you could start unplugging electrical connections to the intake manifold while the car is running. If the idle changes then that part is likely to be working properly. If there is no change in idle when a part is unplugged then that component may likely be faulty. Any part you believe to be bad could be replaced to see if the car runs correctly. This can be time consuming.

Please use common sense and take everything I've said here with a grain of salt. If you have to, consult with a professionally trained technician.

(A trick I learned was to spray brake cleaner lightly around the manifold where any vacuum leak is possible. If the engine RPM's go up when you spray in a certain location there is a leak there.)

the mani i had on the car was 4 point injection from a d16a6 and yes the car ran good. iv tested for leaks and cant find any. i was thinking thats the idle might be set to high on the set screw and its like trying to correct it like over compensation or some thing. it doesnt seem to make a differance what sen. are pluged in so i guess ill take all the sen. off my a6 mani and put tm on the new one

You never hooked up all the sensors? Again, what new manifold did you use? You are not giving us a clear picture of what you've done; you need to be more specific. Answers to these questions will better help us know the variables of the situation.

If you didn't hook up the sensors (EACV, TA sensor, Fast idle control solenoid valve, etc.) then of course it's not going to run correctly. One more thing to check may be the throttle cable. The bracket may be mounted on the new manifold in a slightly different position making the cable too tight on the throttle body.

its a e-bay mani. i got it off of a d15b3 block with a mystery vtec head i think is a z6 but i dont know my brother said i need a new manifold cause the one i have on it dosent have a spot for a senser that the a6 mani did he says that i have to get a new one made for my car he also said the gasket could be bad
