From what I gather, the 1988 crx si intake manifold runs its vacuum lines differently than other crx si models. The 88 si model has 2 vacuum connections on the dashpot thing (one pointing towards the passenger side and the other pointing towards the driver side).

Basically I have 2 vacuum hoses coming off the firewall, but there are 3 connections on the intake manifold.


For those that have done the mpfi conversion using the 88si manifold, how did you run the vacuum lines? thanks

well i just plugged up the T fitting between the intake manifold and dashpot. seems to idle fine.

I am throwing code 20 however. Electric Load Detector... Does anyone know what I need to do to fix this?

 

Fixed it. If anyone wanted to know the eld thing was bad. https://honda-tech.com/zerothread?id=468260

swaped out the fuse box under the hood and no more code.
