my 98 toyota four runner needed an o2 sensor so i bought a new one and put it in, the check engine light went off but now has poor throttle response does anyone knowwhat the problem might be??
Did you have the battery disconnected when you changed the O2 sensor? Either way you can disconnect the battery for a while to reset the computer and then drive it for a bit. The computer sometimes takes a while to recalibrate when you change a sensor.
