This is somewhat a dumb question but I have a 99 GSR motor, and an OBD1 ECU....therefore my header only has one O2 bung on it with one O2 sensor. My sensor has recently gone bad and the car is running very rich. The question is which O2 sensor to buy? Someone said I can use the top(primary) O2 sensor from the OBD2 GSRs (the second one is just emmisions). Is this true? Or would I want to get an OBD1 sensor from an older GSR or B16? Please help me out so I can order it and my car can run good once again.


Thanks all.

 

bump

 

well if it ain't hard to do then try it and see

and if not then u can always order another but o2 sensors are the same or do the same **** it the ecu that reads them different but since u OBD1 like myself well the it is looking for only one sensor and will read only that for the performance adn emissions


so like I said first try it
it doesn't hurt

 

Very true! But these thigns cost money!

Anyone here of the Denso O2 sensors? My buddy has a Turbo Regal and he said the sensor held up fine with all the C16 leaded fuel he has ran! I though Denso made our stock O2 sensors, but maybe I'm wrong. He said for his Buick they are 20$ and they are quality
