Well, I was given my father?s old ride, a 1995 Ford Aerostar that?s in
pretty good shape with about 127k miles on it, 4 Wheel Drive, and the
3.5L engine.
Today, as I was driving home from school (which is a good 8 or 10
miles from home) everything was going well, or so it seemed, until I
turned on to my home road (about a mile from my house). As I turned
down the road I noticed that the sound from the engine seemed to be
higher pitched. Not like whistling or anything, but just not it?s
regular hum. About 30 feet down the road it started to like chug when
my speedometer got to about 25-30 MPH...I looked at the panel to see
that the check engine light didn?t just come on, but it was sort of
flickering along with the chugging of the engine. I pulled over as
soon as this started, but being so close to home, I wanted to just
make it the rest of the way. So I did, pretty much just riding along
the side of the road with my signal light on at about 20 MPH or less.
When I got to my house I checked out the oil and the antifreeze, and
both were a little low, so I fixed that. I started it up and tried to
see if I could make it to the store down the street. I pulled to the
end of my driveway and in that little distance, I noticed it chuged
once again, and decided not to risk it.
I was just wondering, what kind of problem could this potentially be?
Up until I turned down my road the thing was running fine going about
60 MPH. My battery has been going dead a lot lately, and I?ve been
using one of those portable rechargeable power packs to get it started
until I can get a new battery, could that be a problem?
Any help woul dbe appreciated...

The bad battery is pulling most of the current from the electrical system. By
running it with a bad battery you probably also overworked the alternator and damaged
it. Replace the battery immediately and have the charging system checked.

Ok...so the fact that that battery is pretty much dead would cause me
to have such problems? I know that sometimes it will hold charge (so
the alternator must be good, I assume) while other times it won?t.
Sometimes I could drive to a store, go inside for 3 hours, come out
and it would start right up, while other times EVERYTHING is dead,
even the dome light. I?ve been meaning to get a new battery
anyway...so this should fix the problem?
EDIT: Oh...and I?ve been reading some websites about the alternator as
well (since I?m not really a tech guy). They?re telling me that if the
battery?s dead, and the alternator?s not working, I?ll experience
these types of problems. Just to be safe, should I get a new battery
and replace the alternator? (This shouldn?t be too big of a problem,
because my father owns another Aerostar with virtually all the same
parts that I believe blew a head gasket and is just there to take
parts out of).

You might have a bad alternator. That would cause the low battery and also
make the whine. I lost one once while driving home, not only did it howl
like crazy, it also smelled awful. It's hard to mistake the smell of
burning wiring.
On the same car, I found I could tell when the battery was failing before it
died because the engine ran like hell. Most auto parts stores will check
the alternator and the battery for you if you take them in.
Of course, the chugging problem might be totally unrelated to the battery
problem.
Just my 2 cents.

Well, after I posted that last bit a little while ago, I continued to
read the website that I was on. It talked about how if you take a
voltmeter to the cable connections on the battery while it?s running,
and you get around 14 or 14.5 DC Volts (and not less) then you
probably don?t have an alternator problem. Well, since I had a
votlmeter laying around, I tried that out and had about 14.7 Volts, so
I assume the alternator is ok. Even though the alternator seems ok,
could the bad battery be causing my problem, or is it something more
serious?

You know you have a bad battery. Replacde the battery and see if everything
is fine.

Ok, you know the battery is toast, replace it and see what happens. The have the
alternator tested.You have to do this before you do anything else. It is possible to
get 14 volts from a bad alternator. The current capacity can still be low.You also
need to check, clean and tighten all of the battery cable connections and the
connections on the starter. Until you replace the battery you're just pissing into the
wind.

Well what do you know...got the battery replaced (it was still under
warranty, thank you Sams Club) and everything?s running great. I never
knew that having a dead battery would cause the engine to mess up.
Definitely a learning experience for this kid...thank you guys...

Great. Is that battery from Sams Club a Champion brand? If so, keep the receipt
handy. Those have to be the lousiest batteries I've ever seen. I thought they were a
pretty good deal at first. I had them in 3 cars, 1 pickup, and a garden tractor. They
ALL failed in a litle more than a year and had to be replaced. After getting 2
replaced under warranty, I gave up and bought different ones. Yeah, they were still
under warranty but......
I know other people who have had the same luck. To be fair, I've also seen a few
outlast the warranty period, but I'll never take the chance again.

No...it?s not Champion...some Nascar XLT dealie...it was my own fault
for letting the last one go dead. I have a Sirius Satellite Radio (the
kind that suction cups to your windshield). And I just turned it off
the unit by the button on the front, not knowing that while it was
still plugged in to the cigarette lighter thing, it was drawing out
power.
I should be good from now on...
