I'd sure get a hold of a good scanner or someone with one and look for any misses on number 4 cylinder in it's memory. Look of my posts on this to see what I went through.

Keep in mind that if the light is flashing and it turns out to be a miss that means it could damage your catalytic converter.

Good luck and have a Merry Christmas...

When I went in to look at the history of my cylinder number 4 it had if memory serves (I could go look at my old post) an unbelievable 38,000 number in the history. I don't think 2 misses would make me think anything other then a coil or other ignition problem. It could be the beginning if it started missing and tripping light every time you used it. TPS isn't involved in problem I spoke of that I remember. (As a side note I just cleaned my TPS on a Ford pickup and the TPS cleaner didn't work worth a darn but the carb cleaner works fine. You just have to be careful to not get it on certain parts where the carb cleaner damages the TPS. I used a rag with carb cleaner and cleaned specifically the built up carbon without spraying the TPS. Worked like a charm.)

Tried to attach the video here after I saved it to my hard drive but this forum doesn't accept MP4 from the iPhone.

In your case I'm assuming since the problem is coming back constantly I'd hook up your Solus to live data and just leave it on while you're driving making sure number 4 cylinder is the main thing to watch. Once it starts to miss and trips out the stabilitrak you will be able to see the screen showing the misses freak out. If you care to send me a text message with a phone number I will send the captured iPhone video of what tripped my mechanic friend into realizing that what I thought I had was exactly what I had. I have a GM certified rebuild in my Suburban now. No more problems.. If you tell me how to attach it here I can do that but have never done it before on this forum but will look when my typing is over here...

 

I was googling the same problem
just bought new Tahoe 2019 from local dealer in Saudi Arabia Jeddah
after I paid in cash the car price, and @ zero mile, at the show room when engine started it showed the same problem and they are telling me to come back in few days. they will do recheck at maintenance to fix the problem
they refuses to substitute the car, they didn't provide me a replacement car till they fix the problem , they are not willing to give me my money back I find that ironic when GM commercials speaking about warranty and road help while GM cars disabled and not functioning at the show room
I regret that I bought GM car
this just happened today 27/12/2018

I FILED A COMPLAINT VIA CHEVROLET ARABIA BUT UNFORTUNATELY I DON'T EXPECT MUCH FROM THEM

 

If you Google you can find a website that gives a running list of problems wrong with your vehicle

 

The engine scanner I used was the Snap ON Solus Edge which comes into the video showing the very recent history showing as jagged lines as you'd see on an Oscilliscope. (Press Above Link)

 

I have a short update on the 07 Silverado saga posted 11/14/18 and again on December 12, 2018. On New Years eve my son took the pickup to a friends - it was below zero out and windy. The engine light came on and stabilitrak popped. My wife and daughter took our suburban to him and brought the Silverado home. New Years day I put it in the garage and pulled the code - misfire. I pulled the #1 and #3 plugs - #3 first - it was fine. #1 was fouled and likely the misfire. In the previous repair I had replaced the plugs (11/14/18) so they only had 1500 or so miles on them. I decided to try a coil pak - hoping/praying the pak is weak and allowing for the fouling plug. I replaced the plug and put a MSD pak on (cheapest one I could find in town - $67). I cleared the code and ran the truck - all good. It has been that way so far - probably about 700 miles on it. I am hoping/praying the coil paks are getting weak - it does have 307,000 on it. I may pull the #1 plug and inspect this weekend. If all is OK, I plan to order coil paks for the rest of the cylinders.
