evaporator emissin leak small

I have the same problem with mine, plus a rough in-gear idle and it stalls one second after start up after warm. I believe it is a failing fuel pressure regulator, losing fuel pressure too fast, and possibly resulting in a small EVAP system leak. The FPR is under the airbox, and not very easy to get to. I'm going to try a fuel pressure test first.

thanks for your reply! i have no stalling just the p0456.. Let me know how it goes!ok? and good luck.. I hope someone else may have another idea if it is not the presure regulator
