ok.
i found a post that said you could unplug the maf and the PCM will go to a default speed density which allows for any vacuum leaks..in other words...if i unplug the maf and it idles fine, then it means I have a vacuum leak somewhere....if it still idles rough it means its some sort of ignition issue...opti, coil, etc.
sound right?
