Thanks mpoli,
I went out and picked up a 1990 mustang 302 o2 sensor as per this article:
http://business.baylor.edu/Richard_Easley/autofaqs/o2sensor.htm
for $41.00 after tax, I will spilce it up tonight and install it tomorrow.
This seems to be a likley candidate for all my symptoms from what I have read. Hopefully it cures me.
I also noticed in my reading here that ideal conditions for an older cat like mine are well heated up and run hard right up to the actual test, which I did not do. (The plugs & wires are from this last summer and I always use 93 octane by mfg recomendation.) So I will do this and keep my fingers crossed.
Anyone out there know if there is a way to test an o2 sensor, out of the car?
And or in the car an running?
