Is this h22 usdm or jdm? I dont think the problem is your tps, normally (from my own experiences) when the tps is shot, the idle will fluctuate and not sit steady at all (you'll also throw a cel). You may want to try adjusting your base idle. It could be as simple as your idle adjustment screw loosened a bit. Its a common problem in eg h22s, not sure if its the same for the actual lude guys.
