i swapped my obd1 b16 manifold out for and obd2 type r unit about a month back. when installing everything i noticed that the obd1 iac valve bolt holes didnt line up on the back of the manifold. luckily my brother had an obd2 unit at the house. so i bolted that on instead. ever since then i havent been able to get my idle under 1500 rpm. now my question is: could the obd2 iac valve be causing all this trouble, or am i overlooking something?
 
id bet you have a vacum line off, or crossed....try to find someone with the same setup and check everything...also, i believe this site has the fixing an erratic idelm go through eveyone of those....haha i must say i've had idle problems one to many times from a bad TPS to a line being off, and even the good ol IAC...
 
i've pulled off every vacuum line and sensor to look for cracks in lines and stuff. i guess ill retorque everything and go from there. fuck hondas.
