just found, someone mentioned shaking wires while its running, did that and it was a loose ground on the negative battery terminal. glad i did that this one really had me scratching my head. i love how it always seems to be something complicated or expensive and it ends up being something like that, at least thats whats happened to me with this truck so far.
