I have a 2009 EX35, I love it.. awesome car.
It just reached 121,000 miles
New Radiator 2 years ago
SO I recently had a P0420
and STILL HAVE a P0455 and P0456 and a P0442
I changed my Left Driver and Right Passenger catalytic converter along with new exhaust piping leading to the muffler.
The P0420 is gone, now I have P0430 !!!
I now want to change all of the O2 Sensors, But I dont want to get OEM, since they are pretty expensive.
Which Aftermarket O2 Sensors are good ?
Hopefully the new sensors will fix the issue
