Default Unplug power from valve

It's only ems. You won't pass test but zero damages to motor also better mpg, power and idling according to Ford engineering relative and guaranteed no more hard starts at the gas pump. Good luck. Zoom zoom

Default I did it in 5 minutes.

I assume this is because there is more air in the gas tank at that point and the stuck purge valve allows it into the intake downstream of the MAF sensor, causing the motor to run lean.

Does anyone else have experience with this problem? Does that sound like an accurate diagnosis?

The dealer wants $200 to install a new purge valve, $140 parts and $60 labor. Does anyone have any experience changing out the purge valve? How difficult is it?

Thanks in advance for the help,

My ‘o8 Miata would stall every time I refueled. After reading this forum, I watched a YouTube video, picked up the part from the dealership ($116) and swapped it with the old valve in five minutes. Refueled without any issue. Now I need to figure out how to clear the Check Engine light.
