OXYGEN SENSORS

[86grdnatl]

Just wondering how many oxygen sensors there are on a 1986 grand national and where exactly they are. I have a code on my car saying that the exhaust is rich and I want to replace the oxygen sensors. I am just not sure of where they are, or how many there are. Thanks alot for any replys

There is one narrowband sensor, in the passenger side header feeding the turbo. Just below the turbo flange facing inward toward the water pump.

Thanks TurboDave, is that the only sensor? and is that relatively easy to get to?

Only sensor and NOT so easy to get to. Takes a 7/8" open end wrench down behind the turbo and above.
