idle h22a jdm prob

[gcmplayer]

I did an h22a jdm swap into my 93 prelude and everything went ok till i turned it on well its not that bad of a problem i guess when i turn it on the idle goes up and down and up and down again and again from like 800-2200 i have no errors no check engine light being reported by the computer and all the vacum lines are in cant think of anything wrong please someone help me?????

it sounds like ur vacumm lines. If your not throwing a code its prolly ur vacumm lines in the wrong places. It might be ur tps, with the car off unplug it and then start the car. if it levels out its ur tps, if not the only other thing it could be is the IAC. idle air control valve. herd of this being a problem but never dealt with it so ask someone else. also did u do your own work or did a shop put it in, because if a shop did it they shud be able to fix it easily.
