Not very "techy"... but very wise, I like the common sense approach.
Thanks !

Perhaps the final test should be to remove the intake hose at the TB,
and
SEE if the throttle plate is in the appropriate position. This would be
as
little plate as possible interfering with the air stream.
I have seen in other makes, a tend to go too far over center by a bit.
Supposedly this would allow some slack in the cable while having the
foot
throttle stop at the floorboard.
Not very techy, but I'm sure this would be the old school type of check.
;-)
Not that I'm old school, just lazy :)
regards,
Mark S

Back in mid-December Paul K. sparked a discussion on Throttle Link
Adjusment, some secret "S-Car trick" that Ray T. performed. I had heard
of
such a trick but never understood it, so I wanted to try it myself
thinking
my throttle probably needed adjustment. I followed the Bentley procedure
first and recorded it in the link below. This seems the right way to me
but
I after I finished I still had lots of slack (same as before) but yet
the
pedal hit the floor at WOT? This seems correct to me as it doesn't
stress
the linkage when pedal is to the floor, but am I missing something on
this
elusive "S-car" trick? Opinions welcome...
A few quick photo's makes it easier to explain:

For those of us running without Audi's over-engineered "comfort" gas
pedal,
it is easy to notice if you have overtightened the throttle cable, as
Tom
suggested.
It is easier, however, to have someone floor the throttle, while you
rock
the throttle linkage to see if there is still slack to be taken up by
the
cable adjustment. Then you will know how much you need to take up, and
then
go from there.
DISCLAIMER: The aforementioned assumes the vehicle is not running,
i.e.,
"off". To be sure, remove all spark plugs, all gasoline, ignition
solenoid, ignition, fuel pump, fuel pump relay, BOTH PSO's, and battery.
The aforementioned assumes further that you generally drive a Honda
Accord
or Ford Tore-ass, and remain unsure as to whether your car is running or
not.

Be careful doing this! Make sure you do not over tighten!
When the pedal is pushed to the floor, the throttle should be wide open.
The adjustment is at the throttle body and is not difficult to figure
out.
Trial and error is a good method. Be careful; if you over tighten, you
run
the risk of breaking the cable or the linkage.

Bill,
Before adjusting the throttle cable, check to make sure your throttle
position sensor is properly aligned. When you just touch the throttle
linkage open, you should hear a click. This, of course, tests only that
the
switch opens and closes "physically", as opposed to whether the switch
properly bumps up the fuel enrichment.
Next, look at the throttle cable. See where the cable mounts atop the
throttle body? See the little metal clip that slips over the grooved
sleeve? BEFORE removing the clip, pull the cable away/straight back. I
bet
100% of the cars on the road (that have not already adjusted their
cables)
need adjustment. How much can you pull the cable back before the
throttle
linkage on the TB begins to swing the butterfly's open? 1/2" or so?
Pull
the clip, then reinsert the clip right before the point where the TB
linkage
begins to actuate the Throttle Position sensor. If the sensor is
properly
aligned, then you will notice that the TP sensor is not triggered until
the
linkage moves ever-so-slightly.
If your car is like mine, Paul's, and all the UrS's with about 100k on
the
clock, you will also note that this may be the last time your throttle
cable
can be adjusted - simply stretched to its limits.
