My check engine light started flashing on my 98 Dodge Intrepid 6 cylinder 2.7L engine and I turned the key on and off 3 times and got these two codes (p 1684 and p0300) I am trying to find out what these codes mean? Also I was going through my manual and it stated that when the check engine light is flashing that it means that there is a catalytic Converter issues and could cause major damage. What could this possibly mean?
**Note**** I changed my oil today the same as I have for some time now****
