Bought O2 sensors... installed and recieved a new diagnostic code stating that the air/fuel ratio was too rich... they tried to tell me that their tech team said that the O2 sensors are working if that message is being sent and that I should take my car to a mechanic. Looking on internet come to find a 38yr mechanic that said my new diagnostic code is solved 99% of the time by replacing the O2 sensors. In other words, their product is garbage or my car is the 1% which has a deeper issue. I let them know I would be contacting paypal, then my bank if paypal doesnt step up and get refund. Their website states that AM Autoparts does not give refunds on electronics (which O2 sensor falls under). I got the refund.
Every email I received was from a different person... the hours of response were at 2am, when the hours listed on those emails said 8am-5pm is normal business hours. Something aint right with this company. Spend extra money for peace of mind and go elsewhere. I even left review on their website. They wont post it. LoL
