well.... i dont have an o2 sensor. but i ran 17 mpg with no o2 sensor anyway. yes this car should have one, but it doesnt.

more and more i think about it, i wonder how it stays running...

Wait, it should have an O2, but you don't have one in it? Well, there'* your problem....

but....

it has got 17 with no o2....

... because the gunk was causing it to run better than without gunk, in your favor... get an O2 on it, it'll pay for itself pretty soon.

i know, especially with one being $18+ shipping for my car. but it needs so much more. if i did that, i would have to redo the vacuum lines <takes a rocket scientist just to be able to read the diagram> and put a new carb on it. i put a new carb on it, i wouldnt need the o2 because i will put the canadian spec on it. etc etc...

and you keep this car because?
