[V8] Fuel Pressure Regulator-Stumble, miss

[Korn, Bob]

Anyone have a idea of average life span of the fuel pressure regulator on
the V8.  I replaced mine, as maintenance, about 20K ago.  I now have a
stumble or miss under constant throttle position and slight load conditions,
most noticeable at highway speeds.  I'm thinking fuel, as the ignition
system has all been replaced recently.  Maybe a bad injector or two?

Bob

there can be several causes for a 2341 code besides a faulty O2 or its 
wiring. A sticky FPR causing higher than normal pressure is one. A dirty
fuel filter 
causing a poor flow problem is another.
