@Mooseman Thank you! For safe measure, I emailed PCM of NC as well to see if they perhaps know what the idle speeds may be for the 5.3. The steps in the video were what I used during the first round to get the idle to settle down. Should I still attempt that, or force the PCM to relearn on its own by driving around for a few days? Also what kind of values should I be looking for that are considered normal for the 5.3?
