Got my K5 from the shop finally on Thursday and so far so good... they put on a new fuel pump and a new line, both of which I put on a couple weeks ago Anyway... For the last few days (well, since I got it) it's been idling really high.. I'll start it up and it'll go like normal but when I give it some gas, it goes pretty fast... When I'm driving it's normal most of the time, but a couple times on the way home from school I've really had to step on the brakes to stop it because it just wants to keep going... When I put it in park, it races again, and when I shut it off, I can feel the gas pedal push up against my foot like it was down just a little bit but not much... I'm thinking it might be the throttle because my Subaru did the same thing once and we just adjusted the throttle cable, but I can't find it on the K5 (??) and no diagrams of it in the Chilton's book... 79 K5 Blazer Cheyenne.... That's all I have to say about that.
