This month, the focus is on a post from Bob from Massachusetts about an intermittent fault on a 1998 Ford Explorer that resulted in rough operation and a check engine light. The direct cause of the fault was quickly tracked down to a blown fuse (13) and resolved. When the vehicle returned a few months later with the identical problem, it was time to dig deeper and get to the root of the issue. A key piece of information was revealed during the customer interview, which made this diagnostic mystery quite a bit easier to solve.
