using a 1/2 watt resistor and 1uf 63v capacitor. did it both on a 2002 and a 2004 msm and now both cars are getting p0139 (Oxygen Sensor Circuit Slow Response (Bank1, Sensor2)
should i go with a 1/4 watt resistor? that's my only thought.

The wattage rating of the resistor is simply a measure of how much power it is capable of dissipating before it burns up, it doesn't affect the electrical performance of the device, apart from the fact that the resistance will tend to increase towards infinity if you exceed the wattage rating by too much, as the device will undergo a phase-change to the vapor state.
