dose any one know the proper way to redo the vacuum lines......i have a 89 HF and have a 91 IM

 

dose anybody know?

 

What do you mean by "redo" ?

 

he is askin i think how to run the vacuum canisters that are on the firewall to the intake manifold, like what line goes where.... help a fellow ef'er out...bump

 

good question, i dont know.

bump for you.

 

here are vacuum lines in the box on the firewall for HF - you will only need numbers 7, 12 & 21



this is where they are on the HF engine



this is where they are on the 89-91 Si MPFI engine (88 is a little different)



this is 88

 

thanks.......but the other question is where is the EGR valve on the SI?

 

only HFs have EGR

 

because the SI ecu is giving me code 12


(you see what happens when you let other people use you computer... LOL )

 

Oh right Cali... Is it a Cali emissions manual EX sedan MP6 perhaps? Thats the only PM6 I've ever heard of having EGR. Good luck with that, I'd get a non egr PM6. Other than that I dono.

 

Anyone know if I can use these digrams on my 91 civic? I'm getting ready to go MPFI and want to have all the info. I can get.

 

vacuum lines will depend on what engine it is - essentially, for the engine to run right (if it doesn't have EGR) you only need vacuum line from throttle body/intake manifold to the MAP sensor and vacuum line from the intake manifold to the fuel pressure regulator

 

You wouldnt happen to haev that same diagram for a DX would yoe? I am in the same dilemna
