Does my 83 inline 6 have an O2 sensor?
If yes, where is it located. Also, perhaps someone could confirm if this year was computer control capable. I don't see any multi pinned plug for a scanner anywhere. Thanks.

If a truck was sold new in California, the DSO code stamped on the Warranty Plate (1961/79) or printed on the Certification Label (1980 thru today) is 71 (Los Angeles) or 72 (San Jose).

Thanks for that pic. Is that an 83 manifold? And if I have one on my mine, how likely is a faulty O2 sensor to create mild surging while driving? I imagine it's a bugger to swap out after all these years. Prolly heat welded in place.

I think it is pretty unlikely that your Canadian market truck was built to California specs, thus no O2 sensor. FWIW, I have an 83 parts truck with the 300 six and no O2 sensor.
As to mild surging, I would be looking for vacuum leaks.
