Looks like I have spoken too soon about it running great.

Symptoms (other than the slightly high idle that will go back down after a small tap on the throttle):

Miss every few seconds at idle (rpms will drop about 20 on tech 1)
Every once in a while it will stumble and almost die at idle
After coasting, when I get back on the gas, it will stumble and buck until it clear out and runs normally again
Smooth operation in normal driving and heavy throttle

KOEO pressure is 0 psi, slightly over 40 at idle
Both pumps run when tested
Car starts normally

It looks like the book points me to the hoses in the tank (entire new pump assembly was installed in April 2013) or the fuel filter (new installed April 2013), but I wonder if I might have a bad injector (s) too? They're accells that were installed at the same time as my failed coil (Sometime in late 2008 I believe)
