Hmmm, that sux.
I changed N80 Valve, gas cap but still same code:

16839 - EVAP System: Large Leak Detected P0455 - 35-00 - -

Worst thing is, i can feel now gas odor inside the car while driving.

any suggestion ?

 

If you can smell it in your car i bet you need a gas tank. There are several nipples on the top of the tank that can break off and cause a large evap leak. It usually gets worse over time, read my sticky. I believe there is a recall for it now, ask the dealer if your car applies, i think it does.

 

LOL, COOL, ill call them 2mrow. How difficult is fix the problem ?

 

hmmm, but, looks like there is no recall for it:

hmmm, this is happened to me too many times :

MAR 22, 1999 | Recall ID# 59120

.....BACK PRESSURE TO CAUSE FUEL TO BE EJECTED AFTER A COMPLETE FILL-UP WHEN THE FUEL PUMP NOZZLE IS REMOVED FROM THE FILLER NECK......

 

Well that recall isn't what im talking about. If you notice you smell the gas more after you just fill it or notice a small puddle of gas under the car after filling it you most likely need an entire gas tank.......which would really suck. To diagnose it you need to remove the ENTIRE rear end from the car just to get the gas tank down.
