RE: [DML] idle flux / stall / pickup line?

Shannon, What is happening to the electrical side when this happens. The
fuel pump is an electric motor. When Your idling and the voltage drops the
fuel pump will slow down and your fuel pressure will drop and go down also.
It may look like a pump/fuel problem, but you said it was ok when you race
up the engine a little. Then voltage also goes up from the alternator and
your ok. Is the battery light coming on. If so then the voltage is dropping
so low the car thinks you have shut it off.

Subject: [DML] idle flux / stall / pickup line?


Recently after driving (not cold) when I let the car idle (usually
800-900rpm) I
have been getting a weird fluctuation. The following all happens real fast:
volts
drop, oil light blinks on then off, idle drops below 800 then over 1,200. If
I
give it a little bit of gas or drive it, all is fine.

A few times it actually stalled upon stopping at a traffic light after
exiting
the highway. Today it stalled while backing into the garage after the clutch
was
depressed.

I tend to think it could be my fuel pick up line being blocked/collapsing or
the
fuel pump filter being clogged. The reason I think this is because I heard a
buzzing a month back that was coming from my fuel pump/tank. I did the
"twist-the-fuel-pump-boot-trick" (thanks Ken & Josh) and that took care of
the
loud buzzing. Every once and a while the buzzing will return but not for
long.

Am I correct in thinking that it is my fuel pickup line not allowing enough
fuel
to flow?
Could it be something else?
