idle actuator

[ranahan@charter.net (John Erickson)]

It looks like someone bypassed the valve by unplugging it 
(the electrical connection) and plugging the line.  Clean 
it up, find the electrical connector and see what happens. 
 You'll have to adjust the "idle" screw on the back of the 
throttle body if you get the ISV to work.  There is a 
procedure in the Bentley manual.  You need to measure the 
duty cycle (or dwell) of the ISV and adjust the idle screw 
accordingly.

|  Hi everybody. Remember my idle problem, my roc ('88 16v 
|kr) is idleing
|after 10 minutes of driving at about 1200 RPM. You can 
|see a pic of the
|idle actuator (which I took it out a couple of minutes 
|ago) with Bosh
|code 0 280 140 505 on http://www.scirocco.ro/pix/ia.jpg . 
|What bothers me
|is that is says 12V on it and the connector with 3 pins 
|on the left side
|wasn't connected to anything when I removed it. Is it 
|normal ? The other
|to ends on right and bottom were connected to some hoses. 
|Well, what do
|you think ? Now rests in some decarb. solution until 
|morning.
|  One more thing, the hose which comes on the right of 
|the pic was obturated
|with a piece of nylon from a bag when I took the first 
|look under the hood
|and my mechanic removed it as soon as he saw it. With 
|that hose blocked,
|the roc was idleing perfectly, just below 1000 RPM.
|  Any ideas ?
|
|  Thanks,
|  Luci
