Couple months ago Check Engine light comes on, Code say #1 O2 sensor which was replaced with an OEM. Now the 4Runner has a slight surge. When sitting at idle the tach jumps back at forth about 200 rpm. You can hear/feel the surge in the engine. Also has a hesitation when accelerating. Check engine light has not come on since replacement of O2 Sensor. Any ideas other than being raped by a local dealer? Thanks, Jeff
