    SHO Intermitent rough idle

    2018 SHO, 108 hours, just did all 100 hour service at 98 hours. It has done this twice. First time it would idle fine, but when gave it throttle to get on plane it bogged down 3 or 4 times, finally mashed the hotfoot to the floor and it ran fine. 6 or so hours later, came off plane and every 3 or 4 seconds it would miss out on idle and when tried to get on plane it bogged down really bad. Turned the key off, started back up and everything was fine. Running Ring Free and 89 gas. Duracell 31 AGM battery was one year old, checked out good, but talked them into giving me a new one as my livewells would kick off in the afternoons when I started the motor. Electrical/Battery Issue or something else? Thanks

    Battery could have been the issue. I have had Duracell 31 AGM go bad in 15 months. If it persists I would schedule a checkup with a dealer cause it could be a tps issue or similar.
