Ragragtimetime I am going to "Go Over" everything again. Royster, Your Da' Man I was hoping to chime in. I checked it, Took it off and it still idles high. I have a feeling that its the IAC because when I disconnect it, the truck idles down where I can adjust it with the idle screw. I cant find an adjustment on it though. Looks like the spare head and intake I picked up are about to be scavenged for parts. Is this a normal wear item?
