Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

I have posted on here several times about failing my emissions test and several of you were very helpful.

THANK YOU!!!!!

Had high Hydrocarbons. Found a vacuum leak which helped but still failed.

Then I changed plugs and wires, used just a standard stock plug 2 bucks a piece.
Hydrocarbons dropped to a VERY low level. CO was a little elevated but passed fine. NOX stayed almost exactly the same through all three tests.

All in all, about $60 bucks in parts and three to four hours in time.

THANKS AGAIN!!!!! :-)
