Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner till early morning.
Do you know which codes are stored?
Hello again Chris here,
So I assume those warning lights that were on are no longer on?
If the converter is bad there would be low power, catalyst efficiency codes stored. If you remove the upper O2 sensor this would bypass a possible restricted converter.
