CIS-E III problem, idle only no rev

[JOHN BANDY]

Hey Everybody,
   Well I put the 15" of snow we recieved in northern VT to good use,
first having a blast with the 90Q on all the unplowed roads I could
find and , second carving up the powder on the slopes.
   But now the '89 90Q don't wanna run right. On my way to work
tonight, just crusing along, the motor lost all power like I ran out of
gas. At first I thought the fuel pump which has been buzzing loudly for
years finally died. So I pulled over, to find motor idling, FP buzzing
as normal. Step on the gas and when the rpm's get to 1200 it cuts out.
But idles perfect, so I limp to work, 3rd gear 1000rpm 20mph, it was
only a half mile at that point. Get to work pop the hood and start
checking connections. The first one I check is the control pressure
actuator, I unplug it, open the throttle and problem is gone, plug it
back in and problem returns. I unplug it and go for a quick drive and
all is normal, idles ok, power is good.
   So my question is is this thing toast or is it getting a bad signal?
 If it's a bad signal what controls it?   And how long can I drive with
it unplugged.

Thanks for all the help,  John
