Re: ANOTHER "my '96 GMC idles high" thread...

...and we're back. Still idling high, now about 1000-1100 in P and 800-850 in D. In addition to the above repairs, I have since replaced the starter (unrelated), temp sensor, cleaned the MAF, and wire-brushed all the grounds I can find under the hood. Getting abysmal fuel economy (about 9 mpg), but it's not smelling rich, and aside from the high ide the truck runs well. At my wits end about this stupid thing.
