So, I have a 1989 Isuzu Trooper with the 2.6 4 Cyl. and it's been having some problems. From what I've seen and read it all goes back to the IAC valve, but I can't seem to find it. According to the Chilton's guide it should be attached to my throttle body, but it's not there. I think the manual shows the wrong picture. If someone could point me in the right direction of where the IAC is and possibly how to check to see if that's the problem I would greatly appreciate it.< src="http://www.google-analytics.com/urchin.js" ="text/"></>< ="text/">_uacct = "UA-939292-44";

just curious....
 

Were you able to locate the IAC cause I'm having the same issue with the Chilton. I'm trying to clean it up a little
