91 civic w/b16a fails ref smog for emissions only... I made a few repairs, and ready to take another crack at it.
But!!! The o2 sensor is a obdii primary Bosch sensor new. Im thinking of replacing it for a few reasons? 1. It's Bosch and i heard they are crap? 2. It's not the same application for my obd-i set up, but thinking it should work the same?

What you fellow H-T'ers think?1. Replace it for denso or ngk product with correct application? or Take it for round 2 and smog?

FYI> i seen bosch spark plugs used in the past and watched them fail. One of the center elctrode/ spark conductor detached from the unit, which resulted in a fat misfire.


Thanks for any info !
