Like that title says I've got an ej1 with an SiR-G swap and my idle is steady at 2000rpm. Pulled the CELL codes an here's what it's got. 7, throttle positioning sensor. 23, knock sensor. And 41, the primary oxygen sensor heater. Keep in mind I am somewhat new to the fourm and Honda's. This was my first ever swap. I figured the idle would have something to do with the TPS. Opinions please?

 

First, you need to fix everything causing CEL codes. Then, if the high idle speed persists, you will want to look for other causes.

It very well could be a faulty TPS, among other things as well.
