Hopefully, you didn't route the coolant lines into the plenum of the intake manifold, then your screwed. No coolant should be entering into the intake chamber where the fuel and air mixes. Only vaccuum lines should be routed to it,, trust me you'll know what I mean. Coolant lines should only be routed to the IACV solenoid. If you go to any Honda parts website, and search for a prelude parts diagram. It will help you out somewhat. If you still confused, let me know and ill be glad to post a picture diagram on here...
