Anyone else change the front Oxygen sensors on C43?
I have the check engine for both front Oxygen sensors, codes 130, 150 and 155 if I remember correctly (one code for the heater element). Has anyone changed these before? I took a look at them and they are pretty crammed in there. Any tricks?

hey buddy i changed them on my c43 the first on was busted on the front left side, transmission sucked when this o2 sensor was bad,after i put the new one the transmission shifted like a trans when it works properly at its best, after a while i changed the front right one so everything is new.Funny thing i only have oxygen sensors at the front not the rear ones they are plugged, USA have 4 of them, Europe has 2 of them

Awesome, thats the answer I was hoping to hear, no major disassebly required, I got a little nervous looking at the driver side up above the steering assembly. I actually cleaned the MAF Thursday, reset the codes and the Check Engine hasn't come back on, it's been over 100 miles. It usually came back on within 5 mins or about 5 miles. I'll give it a day or so more and hope for the best.
