Ok i swapped a si motor into my 88 hf. There is a little sensor on the back of the si intake mani. that i have no clue what it goes to. Also my car runs but when i floor it it doesnt go anywhere. I have already adjusted my clutch. It revs up fine but when im in gear it doesnt go very fast or fast at all.Also there are like 2 or 3 extra vacuum lines that come out of that black box, also my friends brother sid it could be my eacv or ecv, any help is appreciated [IMG] http://www.imagestation.com/mypictur...=some%20sensor [/IMG]

yea the sensor on the back is for the si's..the zc manifold doesnt have it either...if ur not getting a code dont worry bout it..

did u put in a new clutch when installed...u should be able to tell the condition of ur clutch...
also r u using the si tranny?

 

i think thats your fast idle solenoid... i am about to run into the same problem when i switch to my y8 intake manifold. i have a friend that also says to leave the plug hanging though..we shall see.
