Fm PA DriverMine didn't close properly anymore, it was always open a little bit. So it was recirculating exhaust gases even when it wasn't supposed to, resulting in misfires.

As you noted, the EGR valve is supposed to be closed during idle, or below (((
>est. <))) 1,500 rpms. However, if the EGR valve is stuck open, the issue would exist whenever the engine was slowing, to below 1,500 RPMs -- always. With the resulting sensation of the engine going to stall, when slowing down for a stop, or driving slowly....
