[Shotimes] Re: still having an engine problem, part 2

[Carl Prochilo]

It's funny, I was just thinking the opposite.  Everytime I've seen or heard
of a problem that might be attributed to a fuel pressure regulator, it
turned out to be something else.  I'm still thinking that there is some
electrical problem in Joe's car that's fooling the PCM.

Cheers,
