I showed this to my next door neighbor who is having problems whis his Aerostar O2 sensors - it worked for him as a "fix".

Found it

"I found a generic 4 wire sensor from Bosch at Auto Zone. Bosch #15717. Spliced it in, reset the check engine light and it fixed the problem. It cost $49.95 vs. $200 from Volvo. I couldn't be more pleased"
