what connects to the 3rd runner on the manifold right under the throttle cable mounting bracket.
do i need it, if not what did you do to plug it up.
thanks

 

intake air temperature sensor?? got any pics of what you're talking about?

 

thats where u plug in the pcv valve. If i understand your post correctly.

 

Intake Air Temp sensor, the 96+ Civics have them in the intake pipe. You either need to get a sensor to fit that or put something over it to plug it.

 

did you use anything in particular to plug it up. rtv, hondabond, or custom made plate?

 

check it, you can get creative and thread a brass fitting in there to get a vacuum source. since you have that stupid PURGE solinoid on your fuel rail, that makes a perfect vacuum source instead of running a line all the way to the back of your manifold. when i had my skunk2 manifold, they required a brass fitting to be tapped and threaded in. it was like 2 bucks for a proper 90 degree fitting, and 10 seconds to tap it.

just a suggestion. i would use something non-pliable to seal it, like JB Weld or epoxy.

soft sealants like RTV and hondabond might come loose and end up in your engine. yikes!
