A few days ago my car was running just fine, then it suddenly shut off on me and when I turned it back on it would vibrate the entire car violently. I managed to get it home before it completely shut off. I changed the ignition coils and spark plugs recently, I’ve also cleaned out the idle control valve and changed out all the fuses. I also checked fuel section and it still won’t stay on. Starts but stalls out or doesn’t star. Odm2 has no codes.
