hello everyone. i am back with another issue that i hope anyone can help me with. This code, P0420 Catalyst system efficiency Below Threshold Bank One is what the obd2 came back with right after cel came on. I think it means something to do with the catalytic converter. Hence Catalyst in the code title. But, being I have a 98 Sebring Convertible with the 2.5 ltr V6 multiport fuel injection motor, I didnt know if that code could mean something common with these motors. Any help, info or suggestions will be GREATLY appreciated. It has 107k and it ran out of gas last week. Now I have this issue. Scared again. Thanks!!
