When I drive my car it’s will sometimes starter or jerk a bit when I hit 2000 rpm and about 50 to 70 km. I get the code p0430 every 500 to 1000 km I’ve already changed my calytic converter bank 2 and my oxygen sensor bank 2 sensor 1. What could be causing this and what should be my next move?
Braydon: In addition to dr dome's advice to check for vacuum leaks (the big 3 are the PCV hose, the check valve in the brake booster vacuum line, and the IMT valve O-rings), try replacing the bank 2 (radiator side) downstream oxygen sensor.
If I understand correctly, you already replaced the bank 2 catalytic converter and upstream oxygen sensor, correct?
Downstream oxygen sensors monitor the catalytic converters to confirm they're working properly. So the problem may be a faulty reading from the downstream sensor.
Downstream sensors that fit our X-Types are Bosch15936, Denso 234-4798, NTK 25607.
