Ok I failed emissions again(sniffer test) in my s14. Its a stock S14 with a KA24De with all emissions equipment in place. Before getting it tested I changed spark plugs, wires, distrubutor cap and rotor and oxygen sensor. The MAFS is clean and the catalytic converter is in place. There is no check engine light on either. I failed kind of miserably too. Does anyone have any suggestion? I think I may need a new cat but I wanted to get some more feedback before I just went and bought one. Thanks

Here are the results:
