I've been working on this swap for about a week now, its been a long slow process. The jdm b16 im swapping into my HX is having some problems. I have double checked wiring, clean the IACV, and check multiple miscellaneous options that may give me idle trouble. The engine is having trouble idleling, and its running really rich. could someone please give me some suggestions that i might need to try, thanx

 

Vaccuum leak.

 

we've (me and friends) checked all hoses for the most part. But a vacuum hose diagam would be nice. Ive been searching everywhere but cant find much of anything. I wonder if anyone has experienced the same probs. im having

 

All manifold vaccuum lines are interchangeable except for the brake booster because it's just too big to take vaccuum from somewhere else, so a vaccuum diagram doesn't really help much unless it's for an accord/prelude/OBD0 chassis honda. Get a can of carbeurator cleaner and spray on your vaccuum lines (people say this is bad, I say **** em, it works) and around your throttle body and IM gasket. If the idle surges or drops, then that's where the leak is. Also follow all you lines to see if one has fallen off or leads to nothing.
