Getting a 176 code on my '95 SE MTX and am looking to replace the O2 sensor (closest to radiator). Engine has original O2 sensors with 103K mi. so it's not surprising they might need replacing. I'm just glad it's the one in front right now.
Anyway....looking around, I see several different OE brands. Is there any one particular brand that is believed to be better than others? Prices look to be about $65-90 for single sensors depending on brand.
...and yes, the EGR passages are clean, MAF is new and the precats are non-gutted.
