Just searching around the 'net yielded a few pointers about the TPS
output voltage at idle... seems like most Ford vehicles expect the TPS
to output just under 1 volt. I have mine set to output 0.9 volts via
the throttle plate stop screw. Just curious if this is about right
I know I have to pull the IAC harness off and check the idle speed. I
don't seem to have any flat spots on this TPS, voltage creeps up to
about 4.65 volts if I turn the pot all the way.
One thing you DONT do is adjust the throttle stop screw! whoever
suggested that on the net, should get a nasty virus on their computer
What problem were you trying to 'fix'?
When you get the original prob resolved, set the idle, iac-disconnected,
to 750 rpm, assuming 4 cyl.
I found the only way to really find a glitch in the carbon track is to
use an O'scope.. hardly worth the trouble, considering the low cost of a
Yeh, I'm a Krusty old Geezer, putting up with my 'smartass' is the price
you pay..DEAL with it!
No a while back I had a huge air leak in the intake manifold and
finally fixed it with new gaskets. While I was driving it the leak was
so bad turning down the stop screw lowered the idle a few hundred rpms
and made life bearable for a while. It was my daily driver so taking
the intake apart wasn't an option for me until I got another vehicle
and tore this one down in my spare time. I was just curious if there
was an "ideal" voltage for this model or Fords in general. Seems like
just under 1 volt is the norm. Engine runs perfectly to specs now with
a new set of gaskets and what not.
