Has anyone seen a DIY for throttle body and intake cleaning? I read somewhere that the intake and throttle system on the 7th gen likes to collect oil residue so I would like to follow the right steps to clean it out. I believe there is an idle re-learn that can be a bit tricky? Any help would be appreciated, just had the wife's Acadia in the shop for stuck actuator in the throttle due to the oil and cold weather so trying to get ahead of my 09 with 41k on it. Thanks
