Hi all,
I have a 2018 Max platnium with 96k on the clock. I had the port injectors replaced after they started to leak causing misfires. I guess it was not a small leak, after about 2 weeks i now have a P0420 code, same back as the injectors that were replaced on. It was just taken on a long drive last weekend, was curious if an "italian tune up" would get the cats back to they way they need to be, or i need to look at having it replaced. Cat temp at idle was about 800 degrees, and O2 voltages seemed to be in the normal range. O2 sensors are original to the vehicle.
Any advice is appreciated!
