[QUOTE="Hey Vern!, post: 23527, member: 6399"] I would start with the blinking. Have the battery and alternator tested to make sure they are not the problem. If they test good you may have a bad ground someplace. Hopefully that will solve the RPM issue, too. The P0420 is catalyst inefficiency. This could be o2 sensors or catalytic converters. [/QUOTE]
