    A rattle when driving

    I have an obd 1 not a Bluetooth but there’s no codes. I read that some times if they are bad it would give a rattling sound during acceleration. I used to use premium gas but I switched back to regular when my truck was running rough, but I always use fuel treatment in my truck also.
