The catalyst acts
as a
mixture averaging device so the after catalyst
mixture is smoother over time and therefore gives a better look at
mixture control for adjustment of long term
fuel trim than the pre-cat oxygen sensor.
This is not a big deal when the engine is running (worst possible side - effect: higher
fuel consumption), but can prevent the engine from starting
as the engine reacts more sensitively to changes in
fuel -
mixture during the cranking phase.
On the other hand, a spark plug which is too cold, will tend to not burn all of the air
fuel mixture within the cylinder, which also means worse gas mileage and sub-par performance
as well.
As @Fred Wilson mentioned in his comment, if the MAF sensor that you replaced isn't the one made specifically for your car, then it won't be able to correctly control the air
