Wife's Focus has an intermittent stumble, particularly when accelerating from a stop.
New plugs and coil packs, fuel pump works fine, fair amount of pressure in crankcase at idle (suspect PCV issue and/or PCV hose is cracked).
She drove it a couple of times and it stumbled, stalled, then threw a code which I accidentally erased before I could read it (thanks Mac tool scanner).
I drove it 3 times since it cut out and it never stalled or threw a code for me, despite putting it through the paces and through heavy traffic (thanks Toronto construction).
R&R of the PCV is a b!tch 'cuz it's tucked under the intake manifold (thanks Ford)
Any suggestions before I attack the intake?
