What is wrong w/my car?????? Group: alt.autos.4x4.chevy-trucks Date: Sun, Mar 7, 2004, 1:33am (EST+5) From: snipped-for-privacy@netscape.net (Gunes) I was driving my 97'Blazer all day today until sudden on the HWY it started picking up on speed by it self w/cruise control being off. By the time I made it home, I could not even use the brakes. Even stepping hard on my brake it kept still moving forwards. My neighbor check the pedal, but was not stuck. He said that something is definitely stuck there, it idles very high. Does anyone could tell me what problem I have here??? There was also some kind burning smell (like metal or so) thanks in advance was the brake pedal really hard to push? if so it sounds like you have a vacuum leak. i would first take the air duct off of the throttle body. then you will be able to look at the throttle plate and see if it is open. if it is jst unhook one cable fromit at a time to determine if it is the throttle cable or cruise cable. as i said i doubt it is either, if so, start the engine and listen for a sucking sound, or look for a hose that's unhooked or cracked. best of luck. -pete
