NEED HELP! Car idles wierd

[Blk_Dc2]

i have a 94 civic dx with a 96 ls swap just changed the intake manifold so i did not have that extra sensor on the top i have tried 3 iac sensors the car idles from 2000 rpms and drop to 1000 rpms and them back to 2000 rpms and so on or sometimes it holds at 2000 rpms and only drops once in a while to 1000 rpms also i only throw the check engine light after the car warms up.
I think that i have a 92 integra wiring harness please help

# 14 says iacv on a diff forum i understand that easier ... i say try unplugging it and see wut it does ...if it makes it better try switching w/ tps plug

Sounds like you may have a Intake Vacuum leak. Spray asome brake clean around the intake & throttle body gasket, & also spray around the intake manifold itself. If you find the car to bog when sprying brake clean in a certain spot, that means you are pulling additional air into the intake stream, & the IAC valve cant settle the idle speed because there is too much air getting in the Intake stream.
