  1. I've changed the one on the intake: https://www.rockauto.com/en/catalog/chevrolet,2016,colorado,3.6l+v6,3315153,exhaust+&+emission,vapor+canister+purge+valve+/+solenoid,4936 As well as the vent solenoid on the vapor canister: https://www.rockauto.com/en/catalog/chevrolet,2016,colorado,3.6l+v6,3315153,exhaust+&+emission,vapor+canister+vent+valve+/+solenoid,16992 I forgot to mention I've changed it already. I think I'm going to have to smoke the system to find the leak. Sent from my SM-G965U using Tapatalk
  2. Hey, one year later and I find this! My truck has the low rpm stumble too. I've been chasing EVAP issues. To date I've changed spark plugs, MAP and MAF sensors, O2 sensors (position 1 on both sides), the gas cap, and the solenoid in the EVAP canister. My issues started at 95k and have been lingering and I'm nearing 120k now. I have a 2016 V6. For codes I was getting the code for a lean condition on bank 1, but that stopped after the MAF, MAP, and O2 sensors. The gas cap stopped the Tighten Gas Cap message, but now I'm getting an occasional P0455 code. Have you fixed your truck? Did you ever solve the rpm stumble? What have you changed or checked?
