serios problems here guys. i swapped a sohc zc into my hf, and i've got vacuum issues. with the egr vac plugged up, it doesn't wanna stay running, but if i plug it into where the map vacuum goes on the intake, it runs good for a few minmutes, then the idle is all over the place and i throw a code five and three, of course. so, anyone else have issues like this, and how did they fix them?? im at a loss
