I have a 2015 High Country…
I have a 2015 High Country Chevy truck. I have 100,000 miles. My truck stat running bad when I got to 70,000 miles. The issue is that the when the truck is stop for a long time then the check engine light comes on. The code read to replace the idle control sensor it was replace and the light came back on. The transmission jerks at times. The check engine light comes on and off. I haven’t did anything to the transmission yet. Tell me what you think. Thanks
