Even with only 5k on them, given the condition of your main cat, and the fact that your HCs are still high (though passing at low idle), I'm betting that you've been blowing high HCs for a while now and your plugs may be pre-maturely toasted. I really think you're dealing with a lack of proper combustion (i.e., poor ignition). High HC pretty much means unburned fuel is making it through the entire exhaust system. I don't think there's anything that will destroy a cat like yours was faster than high levels of HC. |
