    I went to start up the Blazer today and the idle is way too high. I don't know how high(no tach), but when I put it in drive, the tires try to spin. I was on ice, that's why the tires were spinning, but it's never done this before. The idle won't kick down either, the RPMs just get higher if I give it some gas while in park. All the linkages (carb, pedal) seem to be moving freely, so I don't know what it could be. I also now have to put it in drive to shut it off so it won't run on. Any suggestions?

    Thanks,
    Brian

    it sounds like the high idle cam is stuck on the carburetor, is the choke opening up likes it is supposed to, or the vacuum pulloff isn't working on the choke. it depends what carburetor and choke set-up you have. try spraying some carb cleaner on the throttle shafts and linkage, check for any broken/loose vacuum lines.

    Thanks for the reply 95 Silverado, I got it fixed!!!! The rod that goes from the linkage on the carb to the diaphrahm near the firewall was hung up on the loop it goes through. Whew! I'm glad it was something easy.
