Perhaps its time for a new oxygen sensor?

You can use the 1990 Ford Mustang GT (302 motor) oxygen sensor and just splice the wires. This is what I did on my 190E 3.0. I used a universal one on my 420SEL.

There will without a doubt be those who will chime in and denounce me but the Mustang part is the exact same thing aside from the end connector and about $60.
