Failed Emission Test

Best way to go??? Go to an autoparts place like pep boys or something...
Get a can of the stuff that guarentees you to pass. It works! My car
just wasnt going to pass no matter what, the levels were off the scale,
and no hope of getting it back unless I did internal changes. I figured
I had nothing to lose since they guarentee the stuff. Poured in the
bottle, followed the directions, went through and not only passed but
passed easily!!  Amazing!
Not knowing whats in it though, I changed my oil almost immediately
after going through...
YMMV but it worked wonders for me!
