Cold Idle Problem

By JNav93
- Mon Aug 24, 2009 11:20 pm #139621 So i just bought this car a couple days ago and the engine runs great its a 99 dx motor( no vtec ) Sad but a mini me can fix that.. but the only problem is when i start it up cold it idles up and down between 1500-2300 then once at normal temp it runs fine.. idk if this means i have a bad FITV or just maybe clean it out? what do u guys think?
