im doing a single cam vtec head on a dx block.everything isgreat, it runs but isway too rich in fuel. its throwing a code 14 (IAC). i did the 2 plug conversion and switched the 12 and 14 pins on the ecu, but it still is throwing the code 14 and idleing extremely rough. any help here would be great, ive done everything possible with no conclusion to what the problem is, i even bought a new iac. please help!!!

rough idle?

try timing, and spark plug order. may also have a leak on your IACV

clean out ur eacv with some carb cleaner or brake cleaner...i would start with that...then like he said above...check if you have leaks round there...make sure your two bolts ho,lding it in is tight.....later
