Have you tried swapping the fuel injector from cylinder 2 with an injector from another cylinder to see if the miss moves with the injector? Tester ---

Leak-down test. Apply compressed air into a cylinder while the piston is at top-dead-center. This will indicate if there’s a problem with the valves, rings, head gasket, etc… Tester ---

If your engine is the 3.0L flex fuel model the purge valve [http://www.autozone.com/emission-control-and-exhaust/canister-purge-valve/duralast-canister-purge-valve/ford/ranger-2wd/1996/6-cylinders-u-3-0l-mfi-ohv/184293\_658681\_18278](http://www.autozone.com/emission-control-and-exhaust/canister-purge-valve/duralast-canister-purge-valve/ford/ranger-2wd/1996/6-cylinders-u-3-0l-mfi-ohv/184293_658681_18278) may be leaking and causing a misfire on cylinder 2. That valve is located on the drivers side inner fender near the battery. ---

In that case remove the valve cover and check for a tossed rocker.
