Went to take my 4Runner in for smog and failed, high idle passed but low idle had 345 ppm HC. 220 ppm and under is passing. Still have some stuff to go through but while I was checking my cat I noticed that it was completely empty. Did not expect that. So if anybody wants and empty cat let me know. Lucky me I have my backup cat from my last rig. Still have to finish my tune up but at least I solved one problem.

 

Quick update, Put another cat on from my old 86 and set the timing and it passed with flying colors.

 

Maybe look like it burn up or those high flow they been talking about...

I just did mine last week. It passed. I have one problem though it still end up passing. Guy said it was my fuel cap was bad. Got it replace and seem to run even better and my mileage seem to improved...
