[Chad's ZL1]

So this past weekend I was coming back from Modesto from a show and was doing about 80 or so and all of a sudden my car beeped at me and said reduced power for something? It all happend fast. Couldn't drive over like 25mph and the car was shaking too like it threw a rod or something. I have a 2014 ZL1 and it only has 7000 miles on it. I pulled over to side of road looked in engine bay no leakes or disconnects. Thought I was going to have to call onstar and get towed, but I started the car back up reved engine a few times and everything seemed ok. Got back on highway and was able to drive normal home. I only kept it at 65mph though. Since then I have been driving it like normal, even punching it here and there to see if it happens again. Nothing........thank goodnes. But I'm stumped. I did replace my throttle body and put a catch can on about 3 weeks ago...
Any comments would be appreciated..
