I keep getting error codes 105, 150 and 170. I have replaced my bank 1 and bank 2 oxygen sensors, however these error codes keep coming back after clearing them I even replaced my Mass air flow sensor (with another that wasn't brand new). I bought the car and the previous owner had removed the Exhaust ends or something for more power so now it sounds really loud like a muscle car!! Could that be the problem? My check engine light is on and I'm unable to smog my vehicle to register it fully in my name legally so now i"m driving around with bad tags... I don't have money to just throw away and work hard for everything I got. I am unable to buy parts on a whim any longer if it is NOT the real source of the problem... HAS ANYONE ELSE had similar problem codes on there CL500 2001? The first code that comes on I noticed after my check engine light turns on after reset with OBD is PO105. The next is PO150 pd . <- i'm unclear to what the (P) and the (d) mean after the code? Does that mean UP stream And Downstream are crossed? Because the last code is PO170 pd??? whats up with the pd? I feel so dumb...
