i recently finished the mpfi swap on my 90 crx dx. i got an si manifold from an 88 crx si and i got everything done. it runs good, but i have two lines that are supposed to go to the egr valve i think. without the lines it makes my car idle at about 3000. ive tried hooking them up many different ways and it throws a code if not hooked the way i have it.

if someone could just give me a pic of an si manifold that shows the vaccum lines, that would be great. preferably a mpfi swap pic. thank you
