Disregard my silly comment above regarding the click sound...that has nothing to do with it. The scan show code P0420, "Catalyst System Efficiency Below Threshold (Bank 1)". Looks like I need O2 sensors or possibly a cat. I typically go with OEM for these type of parts. Let me know if there is an equivalent brand that you would recommend.
