checked everything i thought possible.....

for those that had the problem... what was the fix?

 

The evap code, means that you had a pressure leak in the fuel system. This can be caused by putting gas in the car and not tightening down the gas cap all the way to where it clicks. It may go off by itself but, I would just disconnect the battery for about a half and hour and then reconnect it. The code should go away, but if not get it cleared through autozone. If this does not fix the problem and light still stays on, it could be a result of your vent control valve and carbon filter box that works with the emissions. Then you might need an idle air volume relearn, which I highly dought you need that. Good luck man.

Mine was the gas cap

 

good deal, and an easy fix, but cost a customer $78 an hour to have it diag and a tech to turn the gas cap and click it then reset the SES code. NEVER PAY FOR DIAG IF THEY ACTUALLY NEVER FIX ANYTHING.........and if you ***** enough you can get stuff for free, try it some time.
