Negative Positive
Title: Threw code p0133 p133
Review: I don'y normally review things on this site, but after my experience with this junk, I hope I can save someone a headache. Don't buy it. Plain and simple, I put this in because my old 02 sensors failed from a bad thermostat which cause the truck to run rich and foul the sensors, put these in and a week later threw both of these codes, checked the wiring, checked for an exhaust leak, nothing. finally, tried an acdelco o2 sensor. code has not come back on since. if anything i think the acdelco one is only $5 more, and is what came factory with most gmc vehicles. save time and hassle and just spend the extra money. believe me, its worth it.
Is the review positive or negative?
