Hello

I have a 1997 850 wagon with non-turbo engine and 5 speed, with 124,000 miles.

I had codes PO131 and PO137 come up, and replaced both oxygen sensors and the catalytic converter (sulphur smell). I also attached the adapter wiring from FCP Groton.

After completing a drive cycle, codes 131, 135 and 137 appeared.

I've checked for cracked hoses and vacuum leaks, but found none. Rechecked wiring connections - all are tight. Car runs extremely well, with average gas mileage.

I appreciate any input.

Thanks

Reset and drive again.

I had to reset mine 3 times before it stopped setting codes.
