is it possible? If so where would the wire (that goes to the o2 sensor) go? this is on an 85 gs w/12a motor. Dunno if this is possible or not

 

where are you in va? In over in Norfolk most of the time. Anyways, if you really wanted to, you could weld in an 02 senor fitting to the exhaust right past the manifold, and install an o2 sensor. Wouldnt be very hard at all I would think.

 

12A cars don't have O2 sensors stock. The best thing to do would be take your manifold to a muffler shop or something and have them drill and weld in an O2 sensor bung. It's just a nut the right size and pitch that's welded on. Then get an O2 sensor from any junkyard for a few bucks. Wideband sensors are better and pricey, but that's the cheap way.

 

widebands are great with EFI...not really needed with a carbed 12A.

 

Nah, i thought i read that the latter 1g's had o2 sensors. I guess i read wrong. ONly reason i asked is cause i already have an autometer A/F and was wondering if it would work. Its not worth it for me to do all that extra work. Thanks for the info anyways though.
