O2 sensor
Hi everyone. a few months ago I changed both of my primary O2 sensors on now 2002 CLK55. I purchased them from autohausaz and they are the car specific ones for this car not the universal ones. I kept getting P0135 heater circuit malfunction on bank 1 sensor one. I kept getting this a couple of times a week. so recently I bought another sensor again the specific one for this car for the bank 1 sensor 1 and also bought two new ones again the ones for this car for the secondarys. I changed the bank 1 sensor one with the new one and the rear ones with the new ones too so now all 4 sensors are brand new. but now I keep getting P0130 error code. I have driven on the new sensor for 110 miles and the errors keeps coming up every other day. any advise is appreciated. My MAF is also less than 6 months old. another symptom that I had was that some times I would turn on the car (once in a while) and the rpm would be spiking and dropping very drastically and I just shut off the car and turn it back on right away and the problem would disappear and I got the P0135 and P0120 which is throttle sensor malfunction but my throttle body and my throttle sensor are also less than 8 months old.
P.S all parts are oem no aftermarket here at all and all parts are brand new.
