Not sure if this video does any justice as a reference to what’s going on but today I went back to go do the brake lines on my truck as they’ve been out the abs module for the past week (just had a baby). Went to start it no lights no nothing, first thing that happened was the negative terminal blew the fuck off somehow within the time I left, replaced that. Started shitty with an insane tapping and then died when I accelerated in park with the battery light. Probably need a new battery and to take off all the auxiliary bs the last owner had. But it started, but rough, eventually evened out but still pulsing but the entire time and even now the oil pressure gauge is bouncing high and the fuel gauge is bouncing as well. Could be a blown fuse (s) issue from when I had the battery disconnected while doing repairs the last week or a cluster issue. Really blown away because this engine ran like a gem since I bought it and this is unlike anything I’ve seen yet. Pulled some parameters on it and one o2 sensor definitely needs replaced and the one of the stft look pretty lean to me but it’s kinda hard to follow everything through my scan tool. Has anyone experienced something similar?

Gloomy day today fellas
