2019 GC, 37K miles, erratic idle
Need a little help figuring out what is going on.
The van seems to idle just slightly over 600 RPM and cycles about 30 RPM up and down when cold or hot. Also, once in a while after idling in gear at a traffic light in gear, the RPM will slowly climb to about 900 RPM and then fall back to just above 600 RPM. Any idea what is going on? Does the TB need to be relearned? And, if so, does anyone here have the relearn procedure?
Thanks in advance for any help or suggestions.
