Power loss

Does anyone know how I can disable my MDS on my 2012 Ram 5.7 Hemi? It’s hesitating and the idle is getting rough not to mention loss of power. If I get in it really hard it will throw a check engine and then run really bad. It throws code P0305. When the light goes off it gets better but still runs like crap....I’m lost

I am not a 2012 guru, but the rough running is causing the code po305 (misfire on cylinder #5) not the code causing the rough running. Pull the spark plugs and inspect..

Welcome to HTC.

Pull the plugs and inspect if you don’t see anything swap all of cylinder 5 with another hole and re drive if still on cylinder 5 after that then you need to dig deeper and may be loosing a cam lobe which will mean a lot of work
