Irregular Idle

[Slpkntmck]

I have recently installed a cold air intake on my 1991 integra. Since installation, when I first start the car it idles at 2000 rpm. Sometimes it will lower if I let it run for a while. But when I go to drive it every time I put it into neutral and come to a stop it idles up and down between 2000 and 1500 rpm. If somebody could give me any ideas as to what the problem is I would greatly appreciate it. Thanks in advance.

did you take any vacuum lines off?

sounds just like a vacuum leak

mine does same when i installed the boost gauge. leaks a little tiny bit

What kind of intake was it? I mean, was it a cheapo eBay intake?(or something similar) Because I know a lot of eBay intakes don't come with the little fitting to plug the vacuum line into.

Just a thought.
