Terry,
I've been running my MSD 6T with a soft touch since 89.A
So what are you running ?A
Curious minds want to know.

A A Hi all
A A Last fall, I commented that my engine wasn't running well.
Symptoms may
A A be found in the e-mail below, and consensus was that they sounded
carb
A A related, or perhaps timing related, and a number of people offered
A A suggestions. But the symptoms were sort of strange and didn't seem
to
A A perfectly fit any of the theories as to the problem.
A A On a whim, over the winter I changed the MSD 6-AL electronic
ignition,
A A since I had a spare and since the last time it failed, it gave
some
A A really weird symptoms; erratic and sporadic problems. I sent the
box to
A A MSD over Christmas for analysis and they confirmed that it failed
their
A A test and had some issues. OK, sounds promising but was that the
cause
A A of my problems?
A A It's been a harsh and snowy winter, but it has rained all week,
which
A A cleaned most of the salt from the roads. So I took the car out
today.
A A I'll feel better after a longer trip, but the first impression is
very
A A positive. The hesitation and stumbling is gone, no starting
problems,
A A and the car ran very very well. I'm cautiously saying that the
problem
A A has been fixed.
A A I wanted to leave for posterity the fact that when the MSD box
fails,
A A it isn't always catastrophic. It would actually almost be
preferable if
A A it would, since I have a spare it and it would make the problem a
A A little more obvious. When they start to fail they get flaky -
symptoms
A A that come and go. Both times they have failed I have started by
A A inspecting from top to bottom my carb, since the symptoms pointed
in
A A that direction. Have an engine problem that you can't eliminate?
Try
A A looking at your electronic ignition if you have it - it can cause
all
A A kinds of weird running issues.
A A Thanks to all who answered
A A A Anyway, my engine is not happy. This morning in the hotel
parking
A A lot I
A A A really thought that we'd have to skip today's event because it
A A wouldn't
A A A start and didn't sound like it was even thinking about
starting.
A A Took
A A A probably 5 minutes of crank-wait-crank-wait before it fired.
A A Yesterday
A A A at the gas station it took 2-3 minutes to start, something
that has
A A A never, ever happened before. It is really hard to describe the
A A problem
A A A so much of it is "feel", but I'll do my best.
A A A A few weeks ago I noticed that the engine would tend to
stumble if I
A A A would floor the throttle, then clear its throat and pull. For
A A example,
A A A I like to heel-and-toe, just because, and when blipping the
throttle
A A it
A A A would stumble instead of rev. The engine also felt a little
rougher,
A A as
A A A though it vibrated more than I remembered it. I don't remember
if
A A this
A A A was before or after I did a short tune-up, by adjusting the
valve
A A lash
A A A (I have mechanical lifters), and cleaning the K&N air filter
by
A A A applying K&N filter oil, etc. or if it is irrelevant. So I was
A A messing
A A A around in the engine bay recently...
A A A This weekend the engine felt considerably worse. It felt like
it
A A would
A A A stumble under partial throttle as well. It would stumble a
little
A A bit
A A A under trailing throttle going downhill as well, so I don't
think it
A A is
A A A a clogged fuel filter.
A A A Oil temp is perfect. Oil pressure is perfect. Water temp is
perfect.
A A A The engine idles perfectly. But if you floor the gas from
idle,
A A it'll
A A A stall. The engine doesn't feel crisp, it feels bloated and
soft, if
A A A that makes sense. It feels rough, and it feels like it
occasionally
A A A stumbles under constant throttle at highway speed. It pulls
hard
A A when
A A A accelerating, but I don't think as hard as it used to, or as
high (I
A A A have a 6500 rpm limiting chip in the MSD that it used to pull
very
A A A easily to).
A A A Suggestions for where to begin looking? And other info that
would
A A help
A A A in troubleshooting?

A A A Subject: Re: [DeTomaso] Unhappy motor - looking for
suggestions
A A A Hi all
A A A Last fall, I commented that my engine wasn't running well.
Symptoms
A A may
A A A be found in the e-mail below, and consensus was that they
sounded
A A carb
A A A related, or perhaps timing related, and a number of people
offered
A A A suggestions. But the symptoms were sort of strange and
didn't
seem
A A to
A A A perfectly fit any of the theories as to the problem.
A A A On a whim, over the winter I changed the MSD 6-AL electronic
A A ignition,
A A A since I had a spare and since the last time it failed, it
gave
some
A A A really weird symptoms; erratic and sporadic problems. I sent
the box
A A to
A A A MSD over Christmas for analysis and they confirmed that it
failed
A A their
A A A test and had some issues. OK, sounds promising but was that
the
A A cause
A A A of my problems?
A A A It's been a harsh and snowy winter, but it has rained all
week,
A A which
A A A cleaned most of the salt from the roads. So I took the car
out
A A today.
A A A I'll feel better after a longer trip, but the first
impression
is
A A very
A A A positive. The hesitation and stumbling is gone, no starting
A A problems,
A A A and the car ran very very well. I'm cautiously saying that
the
A A problem
A A A has been fixed.
A A A I wanted to leave for posterity the fact that when the MSD
box
A A fails,
A A A it isn't always catastrophic. It would actually almost be
preferable
A A if
A A A it would, since I have a spare it and it would make the
problem a
A A A little more obvious. When they start to fail they get flaky
-
A A symptoms
A A A that come and go. Both times they have failed I have started
by
A A A inspecting from top to bottom my carb, since the symptoms
pointed in
A A A that direction. Have an engine problem that you can't
eliminate? Try
A A A looking at your electronic ignition if you have it - it can
cause
A A all
A A A kinds of weird running issues.
A A A Thanks to all who answered
A A A A A Anyway, my engine is not happy. This morning in the
hotel
parking
A A A lot I
A A A A A really thought that we'd have to skip today's event
because it
A A A wouldn't
A A A A A start and didn't sound like it was even thinking about
starting.
A A A Took
A A A A A probably 5 minutes of crank-wait-crank-wait before it
fired.
A A A Yesterday
A A A A A at the gas station it took 2-3 minutes to start,
something that
A A has
A A A A A never, ever happened before. It is really hard to
describe the
A A A problem
A A A A A so much of it is "feel", but I'll do my best.
A A A A A A few weeks ago I noticed that the engine would tend to
stumble
A A if I
A A A A A would floor the throttle, then clear its throat and
pull.
For
A A A example,
A A A A A I like to heel-and-toe, just because, and when blipping
the
A A throttle
A A A it
A A A A A would stumble instead of rev. The engine also felt a
little
A A rougher,
A A A as
A A A A A though it vibrated more than I remembered it. I don't
remember if
A A A this
A A A A A was before or after I did a short tune-up, by adjusting
the valve
A A A lash
A A A A A (I have mechanical lifters), and cleaning the K&N air
filter by
A A A A A applying K&N filter oil, etc. or if it is irrelevant.
So
I was
A A A messing
A A A A A around in the engine bay recently...
A A A A A This weekend the engine felt considerably worse. It
felt
like it
A A A would
A A A A A stumble under partial throttle as well. It would
stumble
a little
A A A bit
A A A A A under trailing throttle going downhill as well, so I
don't think
A A it
A A A is
A A A A A a clogged fuel filter.
A A A A A Oil temp is perfect. Oil pressure is perfect. Water
temp
is
A A perfect.
A A A A A The engine idles perfectly. But if you floor the gas
from
idle,
A A A it'll
A A A A A stall. The engine doesn't feel crisp, it feels bloated
and soft,
A A if
A A A A A that makes sense. It feels rough, and it feels like it
A A occasionally
A A A A A stumbles under constant throttle at highway speed. It
pulls hard
A A A when
A A A A A accelerating, but I don't think as hard as it used to,
or
as high
A A (I
A A A A A have a 6500 rpm limiting chip in the MSD that it used
to
pull
A A very
A A A A A easily to).
A A A A A Suggestions for where to begin looking? And other info
that would
A A A help
A A A A A in troubleshooting?
