Hi everyone, I just want to double check and verify what I'm reading in the Chilton manual for this truck. I have a 1990 GMC SIERRA 1500 SLE, 4WD, 5.7L V8 TBI. I don't know the transmission that is in it (I hope I'm giving enough information here).
The manual says : "The oxygen sensor is a spark plug shaped device that is screwed into the exhaust manifold on V6 and V8 engines, and into the exhaust pipe on the 4.8L" and I just want to make sure that the factory settings should be a single O2 sensor screwed into the exhaust manifold and that it's a 1-wire sensor. Should there be any additional ones?
Thanks so much in advance!
