2025 Tahoe 6.2-liter Z71 engine light flashing, stuttering engine

Welcome to the forum.

You COULD be experiencing the same problem in your '19, but just be aware that this is the '21+ section. There may be solutions to your specific year truck in the pre-'21+ section.

My bad, apologies. I was reading posts and thought I would respond with my similar issues. I will prob post my issues within the correct section. Again. . . . apologies.

My 2025 Tahoe Z71 6.2-liter had less than 700 miles on it when the engine light started flashing and the engine stuttered/fluttered/hiccups at any speed. This is an intermittent problem. The dealership has twice tried remedy this by checking which cylinder is misfiring, but each time I've gotten it out of the shop, the trouble starts again within a day. Help! This is a troubling situation. The truck is brand-new. Is this even fixable?

2025 Tahoe High Country with 6.2 started doing this yesterday. 9500 miles. Took it straight to dealer. I will post what they tell me.

I will tell you that after replacing the coil 3x, they finally replaced the fuel injector and so far so good.
