d15b vtec swap trouble

I just swapped a d15b vtec into my 90 crx si using the a6 enging harness, and a obd0-obd1 conversion harness. The engine runs, but the idle goes up and down. i think it is a vacuum leak somewhere. i need help. thx in advance

vacuum leak...or iac valve. More than likey its just a vacuum leak... check all yur vacum line from the intake mani. there might be one that you forgot to plug or hook a line to.

Re: d15b vtec swap trouble

Try to find an online (PDF or whatever) manual for the car the D15 came out of, and see where they go. You may just be able to cap them off if you can figure out what they're for.
