Hello All,

I found a posting on another list that blames this behavior on the TPS. If
the TPS is incorrectly set or the connection bad, could the idle signal be
close enough to out of spec that the addition of the AC on signal will run
the system out so the computer can't control it?

Any FI folks think this might make sense?

Kim

Deke,

I don't have a solution for you directly, but the problem is tied to the
FI system somehow. Do you have a copy of the Digifant FI Service Manual.
Drop me a note off list if you would, please.

You problem prompted me to look at my FI manual, and some questions have
been raised in my mind, but I will put them in a different post so they
will be archived with a better subject line.

Good hunting, on this one.
