<DIV><FONT size=2 face=Arial>Is it possible or even probable that when the
throttle is closed and the TPS is adjusted where with an ohm meter reads what it
should when it should to cause the idle to to be steady? </FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial> I ask because long ago a fellow who used to
work for Porsche worked at a ford dealership I worked at and told me to bend the
stop tab so that instead of the Bentley instructions all I had to do was turn it
CCW until it hit the stop the CW one * mark. </FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2 face=Arial> It does have the 20 injector clicks key
on and I don't need to move much at all before the 1st click happens. Yet there
is only a bit of clearence between the stop and the arm and I thought perhaps
while running and with a bit of wear in the IAD shaft where the forked switch
that it may contact the stop . Or maybe vibration could cause this. I have the
write up Jim sent and it checked out fine yet this is with the engine off.
</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2 face=Arial> If I recall there is an idle circuit that
even if the wiper is on it the forked switch must also contact the left pin
looking down at the with the cover off of there will be no ground through the
double wiper . This car also had the EGR valve , it seems only the late 72 and
73 in the Bentley use pin 14 at the ECU . Do I need this if I removed the EGR
relay and the old rusted valve. # 14 in the ECU must do something , have no idea
what so I left it thinking it may be a ground .</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2 face=Arial> I sort of understand how the TPS works .
Here's what I see. 12 /47 is ground yet it's only ground on de-cell because
only then does the forked switch contact the left pin the right pin on the
forked switch only makes contact on accel . The what I call idle circuit is
pin 17 . The center contact where the forked copper switch is staked
is always in contact with a double wiper slidding contact to pin 2/14 rides on a
circuit board strip that is connected directly to 12/47 and must be ground on
accel along with the stepped 9 & 20 . Also 2/14 strip on the board has a
break close to full throttle which the double wiper appears to jump across at
the same time as the wiper on pin 9 is just past the enrichment zig zag . It
also appears the cover has it's own stops molded in place . I need to somehow
measure to see what contacts them when. One must stop the wipers from hitting
the plug contacts or they would bend , then again the throttle plate wide open
or closed should I think prevent that provided the TPS is set corrent or close
to it. Yet there are stops in the cover for some reason. Perhaps so one can't
move it to far when it's not installed or too far while adjusting it?
</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial> I have 2 of these TPS ending in 024 or vw E .
One on the car has a wide copper contact the other which I have used has a thin
wire . At some point I recall setting both stops the way he suggested. Is there
any way to know how far the stop should be bent all I recall is bending them
closer to the arm not by a lot and one more than the other. </FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial> For all I know this may have nothing to do
with the issue I have and it's only at idle . It all clears up if I unplug
the IAD temp sensor and if I do that the idle is never the same in park or in
drive it varies 2 to 300 RPM hot or cold. I brought this up because I thought
since when I let off the gas I hear popping out the exhaust thinking maybe the
off fuel circuit is not working proper. Have no issues giving it gas and no
missing . </FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial> I never had trouble adjusting the TPS before
he told me to bend that damn stop . All I recall is if the TPS was not set
proper it would not idle well or it would lag , so long ago I forgot which. Last
time I removed the cover with the TPS still on the IAD and there was not much of
a gap before it hit the stop . </FONT></DIV>
