Thanks for the input. My bad on the AFM cylinders. It's number 1,4,6 and 7. I have another mechanic inspecting the engine next week to get a second opinion. If he will recommend a compression test I'll go ahead with it. I'll keep this post updated
Hi all, 15 Yukon SLT (94000 miles) here So I had a misfire code P300 and engine light blinking late December 18. Done a tune up (replaced all sparks and wires) and everything was fine until a few days ago. Didn't feel any lose of power, vibrations and etc. Got another misfire code, this time P0305 (cylinder #5) a few weeks back. Mechanic looked into it and couldn't reproduce. Had an engine carbon clean up. Again no lose of power, vibration poor fuel economy and so on. Couple of days ago got another misfire P0305. Called the mechanics and he suggested a compression test. Not sure if needed as no other signs are apparent. He also start speaking (worst case) about taking the cylinder out to be inspected and replacing AFM lifters. I've looked into mode 6 on my OBD scanner as saw that cylinders 1,3,5,7 all have misfires, though below the threshold so no codes or lights. Cylinder #5 had count of 78 misfires and the rest (1,3,7) around the 1-5 (thats after a 2hr drive) What I found weird is that the AFM cylinders (2,4,6,8) had no misfires. Aren't those the ones with the lifters? I've replaced the coil of cylinder 1 with 5 and got the same results (higher counts of misfires on 5) so don't think that is the problem. Anyone encounter the same issue? How was it solve? Any suggestions for self diagnostics before its heading back to the a shop? Thanks

flashran replied to Darmichar's topic in 2014-2018 Silverado & Sierra ModsDid you had navigation before? I had issues with gps signals with my iPhone when it was placed close to the screen (like the front cup holders or inside the hidden compartment) when I’ve placed my phone on the center console or near the windshield it’s working just fine. Im with a 2015 yukon myself which had factory nav before I’ve upgraded to CarPlay
I’ll give it a go and see but I do have this problem for some time now and the car been through a few washes since. As I mentioned the adaptive cruise and flashing red lights are working so it seems the system does calculate distance from the car. Also changing the gap settings affects the distance with the adaptive cruise control
Hi guys, Do anyone else have this issue where the tailgate warning (the green/amber car logo on the cluster screen) is always green when a vehicle is detected? It should become ember if you don't keep enough distance from the car in front The adaptive cruise control and forward collision warning works so I assume the system does know how far the car in front is but the light doesn't change.
I've removed the headliner up to the 2nd row rear entertainment. It was quite straightforward although I lost a couple of metal retainers that I need to order now but no biggie. "Luckily" Ive found that the leaks are coming from the rear roof rails bolts. I've retighten them and the leak is gone.
