ive been having trouble trying to trouble shoot a CEL out of my 2002 wrx

been trying a few things, keep driving back to advance auto to have them scan it to see what else is wrong. can tell their getting sick of me and i kinda feel the same way. hah. anybody know a shop that will help me out for cheap? or someone that can lend me a scan tool? i just dont want to pay someone 85 bucks to tell me i have a bad sensor somewhere....

 
why don't you just tip the guy at advance and the sick of you feeling will go away

because he doesn't deserve to be tipped, he told me my gas cap wasnt on tight then walked away, as i was trying to ask him more questions about it

so i went to autozone today hahaha

still the same code, something wrong with my EVAP system

 
My Forester keeps having that code as well. If I make sure the gas cap is real tight is won't come on for a while

 
gas cap seal. make sure threads on gas cap are clean, ditto with the threads on filler neck. they tend to get gunked up and dont seal well, voila you get another effin PO457

 
i'm not sure about WRX, but earlier imprezas are notorious for rust on the very bottom of the filler neck. might be worth checking that too. I had the same code on my RS and that's what the problem was
