my 04 newer body style f150 is pull a code that wont allow me to pass emissions...is there anything at autozone i can buy to pass for now..I will have the issue addressed to a mechanic but for right now I just need to pass. I failed it just a week ago and gas cap said was doing its just job but im pulling a EVAP code. P0442

 

Sorry to say it, but there isn't anything an autozone can have to fix that. The code is for a small Evap leak. That can range from your fuel cap not being in properly to a pin hole in the Evap line some were

 

great...haha I hope its not something expensive to fix!!!

 

does it do anything with the mpg?
