Well...I broke it off.
How long can I drive the car with it disconnected? It's running MUCH better without the darn thing.

 

It's not throwing a CEL?

 

It sure is. It was giving the code which is why I was replacing it. In the process of removing it, it broke off at the threads.

 

its just got one (o2 sensor) - is that correct.
need to remove the exhaust manifold.
and i hate to tell you this - but it it is like my 1988 (1.5), the exh manifold will not come out without removing the head - actually (just thought) , can remove the radiator, then i think it will come out.
have to get the o2 out ; easy-out operation (if that is possible) and install a new O2.
(or a new manifold).
