P0420
Searched around, mostly dead end threads with no follow up. Long story short, 2002, 2.4, 140k mileage. Cruising up the parkway this morning and the CEL comes on. Went to Autozone after work and tbey scanned it with a P0420 code. Looking for possible fixes and or possible parts needed. From what Ive read it could be a bad catalytic. Converter or front O2 sensor. Thoughts?
