its some gay evap gas code
and its supposed to be a leak or somthing with my gas

bought a new gas cap, yet the code keeps poppin up after around a week\

gas mileage hasn't really been too too bad and everything seems fine
i just want that code to go away

help

 

Have you checked the EVAP box? I know some people had issues with that when they put on the Greddy exhaust they had to relocate it. What mods do you have done?

 

i bought the car a month ago from a used car lot

and the only visible mod to the car is a stillen oil cap, lol
but the exhuast is stock

 

Have you checked the evap hoses to the rear left of the plenum?

 

no where are those at?

 

On top the engine is the metal intake plenum. Toward the back on the passenger side there is a small hose connected to a solenoid or switch (IIRC), that has something to do with the evap recycle system.

Do you know the exact code? P0xxx?

 

oh ok, im have to go check it out

i have a recepit from autozone with the code, i just gotta go find it, but ill have it soon

 

the code is P0455

and where do you live in louisiana?
just wondering

 

that code is a nightmare.. My car spent 4 weeks at the dealership because they could not figure out what it was. They would replace what they thought was the problem and clear the code but 50 miles later the light would come on again. I will try to look at my records and recall exactly what is was they replaced to fix the problem. But good luck

 

yea at first i kept going to autozone so they could clear it, and they said all i needed was a new gas cap, did that, didnt do ****.

but yea if you could find out that'd be awsome

 

come on i kno someone has to of had this code before

bumb

 

Is it a regular gas cap or a locking one..if its a locking gas cap it will cause the light to come on due to the vacuum past the key cylinder in the cap.

 

the stock was regular, and the one i jsut bought is regular too

but both dont feel that tight.
like it takes almost no effort to spin them

 

Looks like you may need the dealer closest to you do a evap smoke test

 

whats an evap smoke test?
and about how much does it cost you think?
