Hello All,

I have a 2015 Town and County with 140k miles and a P0430 Catalyst System Efficiency Below Threshold Bank 2. I have replaced all 4 O2 Sensors, spark plugs, ignition coils (I had pin hole in cylinder 3) and the EVAP purge solenoid. I think its important to note the vehicle was in a minor front end collision and the work performed by the dealership was horrible. The entire intake was disconnected and missing an air filter. Not to mention the spare tire is gone. After a long fight, I ended up just fixing it myself. I don't recommend Winter Ford in Dover Delaware.
I am considering replacing the CATs myself. I am do for a DMV inspection in about 8 months. I am looking for any tips or tricks. I cant find anything online regarding a 2015 and I am guessing because its relatively new the information just isn't available yet. So if anyone is able to provide how they dealt with removing the CATs I would love to hear it.

Thanks in advance.
