Hi Brian. First off, our thoughts are with you and everyone else in the Houston area. In regards to the issue with your Blazer, the flood and excessive water plays havoc on ignition and electrical systems. It’s likely that one of the multiple electrical harnesses or sensors are soaked with excessive water and creating a misfire. The only solution to this issue is to either let it dry (which is going to take some time) or try to diagnose the precise source of this issue. My recommendation is to not drive the vehicle until things dry up a bit - as a misfire like you’ve described will likely not cause additional damage - but it could get worse and be even more difficult to isolate and repair. Best of luck to you and all those in the area. Stay safe.
