the idle valve was just replaced so it couldn't be that... could you explain to me where the intake boots are? and if you got some time, i don't really understand the whole vacuum thing i thought vaccums were just for carbs... but know i guess not.
The main rubber tube that the engine sucks it's air in through is the intake boot. If those get any cracks in them, or any of the hoses that are attatched to it or the intake manifold, then the engine can suck air throught them, which is not metered by the airflow meter. So, the engine will suck in more air than it thinks it is, and will idle like crap, and could die. Spray brake cleaner or wd40 around these areas with the engine running, and if the rpm goes up, and the engine runs better, then it is sucking in the wd40 and you have found a leak.
