DTC P0430 Catalyst System Efficiency Below Threshold (Bank 2)
My Check Engine Light is on in my 97 mustang 3.8L. It is throwing code P0430 which says it is Catalyst System Efficiency Below Threshold (Bank 2). What are the steps to fixing this? My car also takes a longer time to start than normal when it is cold. I have to hold the key to start position for like 6 seconds instead of a normal 1 to 2. Anyone have any ideas on what it could be? Also on my car I have been told two answers for which is bank 2. Anyone know for sure what side is 2? Also car is completely stock, no exhaust kit or anything.
