So I've been having these idle problems for a little while now and haven't been able to pinpoint anything...cleaned the MAF, did some logs on the O2 sensors and everything seemed mostly normal?

I had gotten a code for the pre-cat O2 sensor a while ago and it hasn't come back...so I'm not sure if the sensor is bad or not...but it was outputting voltage.

Eventually the car does return to a normal idle but very slowly compared to normal...pushing the clutch in, coming to a stop sign or something, the RPM's will just hang at around 1200...it never used to do this.

Could this be a vacuum leak somewhere? I tried looking around but everything seems OK...
