<BODY bgColor=#ffffff>
<DIV><FONT size=2 face=Arial>Has anyone run across issues with an unstable idle
that clears up with the IAD temp sensor is unplugged ? It only shows up
when there is no load auto trans in park engine warmed up . If I give it gas
from 900 RPM idle speed and watch the tach for lack of a better term it seems to
stuggle until it reaches 2000 RPM. </FONT></DIV>

<DIV><FONT size=2 face=Arial> I first noticed this when I opened the tail
gate with it warm and runing I could hear an erratic miss out the exhaust , it's
not one cylinder . Also if I am driving say 30 MPH and let off the gas quick I
hear a slight popping out the exhaust. </FONT></DIV>

<DIV><FONT size=2 face=Arial> The only thing that seems to cure this is to
unplug the IAD temp sensor . I assume it is running lean. </FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial> It has all the proper E system parts and I
have not found a vacuum leak so far. With the IAD temp sensor connected and
driving under load it seems fine other than the popping . </FONT></DIV>

<DIV><FONT size=2 face=Arial> It has the electric AAR which does close
although it s eems to take longer to close that it used to. I just changed
the MAP to a NOS Bosch # 0 280 100 116. It holds vacuum and the resistence
is within spec. Compared to the old one with the temp sensor plugged in it's
better yet still stuggles with no load . My voltage is 14.3 at 1500 RPM. I don't
have access to read the actual mixture I am just going by the way it acts.
