2019 Yukon Stumble / Misfire, no codes
5.3 6 speed with 80,000 miles. At light throttle there is a noticable stumble that smoothes out with RPMs.. no codes thrown. Just changed the plugs and wires - they were shot. feels like it runs a little better, but the stumble is still there. Based on some forum posts, I decided to change...- mecheng76
