[alfa] fuel pressure

["Scott Johnson" <scott@xxxxxxxx>]

What you are describing are classic symptoms of a clogging fuel filter. 
When the car is off, all the crud settles into the bottom of the filter 
housing. As you drive though, more and more of the crud gets drawn up 
against the filter itself, eventually clogging it, causing fuel pressure 
warnings and eventually a sputtering engine. Turning the engine off 
causes the crud to start falling to the bottom of the housing again, 
which is why the problem seem so intermittent.

Before you do anything expensive or involved I would strongly recommend 
you replace at least the rear fuel filter. Please note that even if the 
filter is new, it can still get clogged up with just one silty tank of 
gas from, say, an old gas station.
