Hi Everyone, hope someone could give me some advice. To make the long story short, I installed a catted X-Pipe last year, and ever since it had the check engine
light on because of Code PO133(Bank1 Sensor 1) and PO153(Bank2 Sensor1). I bought 4 new O2 sensors to fix the problem, but PO153 still remained. I even got a new replacement O2 Sensor for the New O2 Sensor that was on Bank2, but still same code. Mechanic checked, no gas leaks. They don't know what is happening.
I wonder if I should buy the MIL ELIMINATORS, but I read they sometimes don't work or won't have any use on Bank2, and living in Canada it would cost me $100 CAN total to order the ELIMINATORS from the US. Or is the O2 extension on Bank 2 faulty?In Total I already spend $400 CAN on this check engine light, so I'm just wondering if this is a permanent thing that I will have to live with. I do have a scanner and a tuner, trying to switch the engine light of, but it comes back on after 5 miles or so.
