Hello everyone,

My used 2002 Boxster is comes with Free Flow Cat w/ Check Engine Light from the previous owner. I was wondering can I ignore this CEL? Will it affects my car's air/fuel ratio or engine performance? :huh: Thanks in advance

It is always best to use a code reader and get the fault code(s) before deciding a course of action.

I forgot the exact code. But my technician told me it's because of the O2 sensors behind the free flow catalytic converters causing the CEL. Can I just ignore it and let the car keep running without any long term engine problem?
