Front O2 Sensor Problem

mystang428 · November 27th, 2006, 01:24 AM

Recently added longtubes to my 01 GT, then did the sensor simulators for the rear O2 sensors now my car is throwing a check eng. light for the front O2 sensors and a ck that is causing it to run lean. What should I do, replace the front sensors?[/img]

do you have a handheld tuner, Predator or SCT? if you do, turn off your Rear o2 sensors and swap out one of your rear o2 sensors with the front one thats fugged up....if not just buy a new o2 sensor!

There is a differance between the front and rear O2 sensors, so I would not mix them up. If you turn off the rear O2 sensors and the light is still on, then replace that sensor with a new front O2 sensor.
