Could just be a point where the cam and everything else hiccups.

Always a good idea to change out the plugs and wires when you buy a used vehicle unless you're sure it was done recently AND done right.

One or more dirty injectors can also cause a rich condition. The partially clogged injector(s) don't spray as much fuel thus tilting the O2 sensor reading to lean which of course the PCM will try and compensate for by adding more fuel to the equation.
