Will running E85 while I have an emissions test done help me pass the test... I...

...have a 95 Chevy Astro Van.? It has failed for the past 3 years and with lots of repair done. No one can figure out why it wont pass. I have registered it at my parents house for the last three years. (they are not required to do emissions where they live.) Now that loop hole is closed and I need this van for work.

Can your van even run on E85? Your engine needs to be flex fuel capable to run it.
