OK, I am looking at a 1981 Coupe (yeah I know, still haven't found the one I am looking for), the car is located in Texas and I am in Calif, so my concern is smog. The car has the cat. still on it, but the owner said the oxygen sensor is missing and place where sensor plugs into, has been capped with a bolt. Is there a reason someone would remove the oxygen sensor and how hard would it be to replace it. Is there a usual place where someone may have un bolted it and taped it up or stuffed it somewhere, that I could tell the owner to look for.......

I honestly like this car alot and not sure if I should stear clear or not.....

Any help, as always, is appreciated....

Thanks
