my wife's '93 Accord LXA is idleing way too high. When the car is cold it runs fine but when NOT is reached at stoplights it will idle at 1400 RPMs, when it is in Park or Neutral it idles at 2500 RPMs. i tried cleaning the throttle body out to make sure there were no carbon deposits keeping the butterfly open, but that did not help. have any of you guys experienced this or know what the problem is?TIA

 

check for vaccum leaks in the lines...maybe a line broke off or there's a cut in one of the many vaccum lines...better yet, go to a shop to get it checked out like auto zone or something. good luck
