<DIV><FONT face=Arial size=2>Hi </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT>&nbsp;</DIV>
<DIV><FONT face=Arial size=2>I am not an expert but chances are the ISCU could be bad. The ISV should be humming when the ignition key is ON without the engine running.</FONT></DIV>
<DIV><FONT face=Arial size=2>You should try with a good ISCU. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT>&nbsp;</DIV>
<DIV><FONT face=Arial size=2>Continuity means you should read some low ohms. Check the ohms between the leads on your ISV and it should be very low.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT>&nbsp;</DIV>
<DIV><FONT face=Arial size=2>Check also the throttle switch. Contact should be close ( continiuty OK ) when the throttle is not depress and contact should open when you depress the throttle pedal (not fully depressed).</FONT></DIV>
<DIV>&nbsp;</DIV>
<DIV>&nbsp;<FONT face=Arial size=2>Hope it could help</FONT></DIV>

<DIV class=RTE>Hello listees,</DIV>
<DIV class=RTE>&nbsp;</DIV>
<DIV class=RTE>I'm trying to determine which is creating my high idle while in Park and Neutral: the ISV or the ISCU.&nbsp; I measured with my digital multimeter, but unfortunately I've lost my instructions for it, so I'm not sure what it is I'm reading.&nbsp; The Bentley says to check for continuity, but I'm not sure what that means either.&nbsp; Basically the van idles fine with the ISV disconnected, and it doesn't hum or vibrate when connected, so I'm fairly sure that its the culprit.&nbsp; However, I bought a "tested and in good working condition" used one from e-bay, and it hasn't solved my problem so I think it is bad, too, but the seller asked me to measure the voltage at the connector to determine that - and&nbsp;I'm not sure I trust him as much as I trust my old friends on the list.&nbsp; So can anyone on the list tell me what my readings mean? </DIV>
<DIV class=RTE>DC : it fluctuates quickly between .599 and .722</DIV>
<DIV class=RTE>K<SPAN style="FONT-SIZE: 12pt; FONT-FAMILY: Symbol"><SPAN>W : <FONT face="Geneva, Arial, Sans-serif" size=2>it fluctuates between .954 and 1.003</FONT></SPAN></SPAN></DIV>
<DIV class=RTE><SPAN style="FONT-SIZE: 12pt; FONT-FAMILY: Symbol"><SPAN><FONT face=Arial size=2></FONT></SPAN></SPAN>&nbsp;</DIV>
<DIV class=RTE><SPAN style="FONT-SIZE: 12pt; FONT-FAMILY: Symbol"><SPAN><FONT face=Arial size=2>The ISCU looks like its okay - no signs of burnt wires or anything, but I'm obviously not an expert.&nbsp; I looked through the archives already and couldn't find much help, although I know this has been a constant topic.</FONT></SPAN></SPAN></DIV>
