So I'm back with another questionable Ecm problem. So I 100% don't have an oxygen sensor or port in the manifold. This is a 1985 g20 305 federal emmisions. I have an obd port and the carburetor harness but I can't find an O2 sensor or a check engine light location at all. The speedo lights are choke brake and fasten belt but but only the choke lights up.
If this system seems too unrepairable I might just run old school. Any thoughts?
