i have a 1992 Dodge Stealth R/T that idles high for a few minutes untill i start driving, i also failed emissions due to high idle, what should i do?
Check the throttle cable for binding or fraying at the intake, the throttle stop screw for being screwed out too far and to see if the throttle is returning to the proper closed position. Also, look into the throttle body for carbon buildup that might be holding the throttle open. use injector safe cleaner as there is always some build up in there so it's a good time to clean it. Also check all your vacuum lines. Look for cracked, brittle and leaking hoses and replace any that look suspicious. There aren't all that many vacuum lines but make sure they are all hooked up properly. Compare it to the chart on the hood for proper routing. If this doesn't help, then there may be other problems.
