Drove it today and haven't had a problem. When I got home I pulled out a plug and it seems almost completely clean. So perhaps its no longer running rich, but I don't know for sure..
I cannot figure out where this hose goes though. I haven't taken off the air box yet, because it looks like its going to suck. The hose comes off the air box and goes about 4 inches before it hits a connector. Then it is a hard plastic hose that runs about a foot, and its bending appears that it goes under the air box. On the inside of the airbox there appears to be plastic covering where the vacuum hose and this hose would enter. When the engine is running there appears to be no flow through this hose. When the engine was off, i tried blowing and sucking through it to find that air would move both ways. The air faintly tasted like fuel.
If anyone has an idea where the hose goes can you let me know? I can post a picture of it if that would help, but i don't know if it would be beneficial.
Also, I've been reading various site on this and some people say that if there's puffing coming out the oil dipstick it might be the PCV system. Does this make sense, is there a way to check it, or just replace after so many miles?
