Default low idling problem with new 02 sensor

I got my front 02 sensor replaced today under warranty. Now when I'm idling my RPM's stay around 100 RPM's with sudden jumps up to 400 RPM's. It feels like the car is going to stall when in neutral.

Is there any way to manually increase the car's idling RPM's, or is this a bigger problem??

The computer controls the idle and there is no adjustment. I suggust you reset the Engine Control Modual by disconnecting the negative battery cable for about 1/2 hour and press the brake peddle several times for several seconds each time. This will reset the ECM and you should be fine. Dealer should have done this. Ed

Yeah, if Hayes' suggestion doesn't do it, I'd immediately take it back to the dealer as "you touched it now..." But it does sound like it needs a reset.

+1, the car hasn't adjusted to the new sensor yet.
