Review on MOSTPLUS 234 9005 234 4125 Downstream Compatible by Darius Carraway

Purchased and installed on a 2004 Honda CR-V. Unfortunately this product does not work after setting and resetting the check engine light several times. I keep getting error code p0134. I also monitor my car so I'm pretty sure this product is the problem. Order Denso now and upgrade if that solves the problem. Was hoping these would work. They looked like decent quality when they arrived, but they're useless if they give out codes right away. Can I get my money back?
