Re: adjust idle speed without tach
Looks like someone used a "Poor Man's dress up kit" and just wrapped the hose in some corrugated wire loom. Take the hose clamps off peel it back and see whats underneath. Even if you have to replace the "whole system" it shouldn't cost more than $10.00. Valves that are stuck open or closed can cause oil consumption, low end driveabilty problems, sludging and other problems.
