hey,
I got an S14 sr20det and it has been working great the last couple days. However, last night when i was driving home, i noticed that the idle for my car is really high. It usually idles around 800rpm, and now its around 1800rpm. The idle doesnt bounce around, it just kinda stays around 1800 rpm.

Also, as i looked at it today, when i start the car, it will idle at 1200 rpm (the rpm it usually starts out at, and then slowly goes down to 800 when warming up) but after a few seconds the idle ramps up to 1800 and stays there.

The engine has been installed for monthes and i have never had idle issues, so does anyone know where I should start looking to fix the problem?

Quick and cheap (so first) check is to check for a vacuum leak. A vacuum leak can cause high idle. Also maybe replace your air idle sensor.
