Hello guys.....it's that time when I need someone's help on here. First time too.

Anyways, here's the 411. I just bought this car 2 nights ago for pretty cheap. It's a 2000 civic ex with a D15b7 motor in it.

Two issues. Fluctuating idle and bad transmission. ( I'm not worried about the transmission ) - Buying a new one within the week.

The idle issue is where I'm stuck at. It's going from about 1400rpm to 2000rpm back and forth. I came across a disconnected plug that was supposed to be in the IAVC, so thinking I fixed it, I plug it back in, no luck.

I've never had to deal with an IAVC and was wondering if anyone can point me in the right direction? Thanks!
