if it is a leak spray the entire area around the plenum spacer with carburetor cleaner and see if the idle changes. if it doesn't, an air leak is not the problem

i was thinkin if i shud do this

[SunnY-D]

im not sure but i've read that u need to use the torque rench to put on the spacer to get even distribution on all sides.. so theres no leak...

ok so0o i did that learning procedure and my car came down to 750 rpm but today again the check engine light came on and the rpm is back on 1k......i realli think i will have to do the spacer all over again.....do i have to put rubber washer in all the middle bolts?

ok make sure you use Super Heat Resistant Silicone. and paste. you can get a gasket but i would put silicone along with gasket if you have one. but make sure you put silicone on both sides of the spacer. then you shouldnt have a problem at all.

^ yeah did you put a gasket in? that could cause some problems if u didnt

when i put my Skunk2 Spacers in I threw away the Factory Gaskets but i sealed it very well with silicone so i had no problems. but your best bet is to get a gasket and use silicone also. if you would have anyproblems you can hear it. it has a distinctive whining whistle sound if you are leaking. and dont forget to use the reverse torqies.
