Brand new TRUCK⦠2024 Chevy Colorado LT 4×4.. Classic Chevrolet Oklahoma CIty OK Extremely Rough Idol, on cold engine start up, You can hear the ROUGH noise it coming out of the Exhaust and feel it in the cab of the truck. After warm up,, at intersections on red lights ,,you can hear and feel the idol miss at times a little bit. The dealership has had my truck for 8 days now. NO positive results to date. They say GM is making them go through a step by step process. The service manager tells me there is a code in one of the cylinders.. but the injectors test perfect. Looking on GOOGLE i see many owners of the same truck with the SAME issue !!!
