bought my 95 GSR with a CEL on, it's #41.

got a new o2 sensor today, plugged it in and CEL came on after 5 seconds of starting engine. What might be the problem? Should I just get my ECU chipped for no o2 sensor?

there's only 1 place for the o2 sensor, right before the cat. the sensor screws in halfway then stops, could this be a problem?

 

bump

 

i got a new sensor but cel is still on. yes i did reset the ecu.

i think ill just get the ecu chipped, im out of ideas
