output diagnostic

[mike mcclurg]

I'm anxious to hear the answer to this one. I have an
'89 100q that is doing the same thing. It is like the
ECU thinks the full throttle switch is closed all the
time. Figure it might be a short in a wire loom or
something like that, but haven't had a chance to test
the circuit coming into the ECU.
What other problems can this cause? Already figured it
might have an effect causing my idle to vary and go
high periodically.
Thanks in advance to the list genius who has a BTDT on
this problem.
