Have a 94 grand am that just started idling high and won't kick down...if left alone to run in that state would burn up... what is it that I need to do?

It sounds like the oxygen sensor is malfunctioning. Which will cause the engine to continuously idle at high RPMs.
Disconnect your throttle cable at the engine and see if that effects the engine idle. This will eliminate any problems with the throttle cable.

Ran my 1997 chevy lumina ls through flooded water...still runs but idles real high without even touching the accelerater and the temp runs high and have to shut it off let cool down before starting...

If your electrical wires got wet, it could cause all kinds of problems. You could have a bad idle control sensor or the idle may need adjusted. The electrical wires probably need time to dry out, if it hasn't been long ago. A bad map sensor can make the car idle high. Do you have a check engine light on now? If so, you need to get it scanned at Autozone for codes. Does the car die?

Accelerater stays on when in gear even with foot of off the pedal,eventually coming down when out of gear.

First, open your hood and get somebody to work the gas pedal while you watch under the hood, and try and determine if it's catching on anything under there. Make sure it's not simply catching on the floor mat or something first. Spray the cable and mechanism with WD40 or any lubricant. If there is nothing obvious, and the lube doesn't help, the cable may be frayed. Inspect it closely. Let me know what you find out.

Chevrolet sprint 1986 idling high trying to find the

If the vehicle is a carborated engine, you would find your vehicles throttle body where the linkage connects for your acceleration. Most engines then have the idle screw very close to this linkage. Though from what little photo's I have seen of the vehicles engine compartment via google images. I unfortunately can not direct you as to where the throttle body on the engine is located.

96 f-150 idles really high

I just solved this problem on my truck after fighting with it for 2 yrs. Mine is the 5.0 though, check your PVC valve and replace if it is bad. After that Take off your IAC and spray down with carb or brake cleaner and scrape all the carbon build up out of it and work the spring inside. you gotta really clean it out though! After that if it's opening and closing easily put it back together and it should work! you might have to adjust the idle a bit to get it all the way. But after doing this my truck went from a 2000 rpm idle down to about a 700! I hope this helps you!!

Well for the person in florida, if you have high idle even when it's warm out then that may be that there is carbon build up on the throttle body/throttle plate and it's causing some hight idle which is known to happen a lot on older toyota's especially. If u open the throttle plate and spray carb cleaner in there and wipe away the carbon deposits with a rag and make that area shiny u may see a difference.... As for the other person in Indianapolis, if you're having the problem during the winter then that is probably the IAC (Idle Air Control) valve which is connected to the intake manifold. If this gets build up of carbon and starts to make the valves stick in that IAC it could cause some irragular idle problems like as u described. I had a very similar problem in my 92 Acura Integra and I replaced the IAC and the problem went away, but i also know that u can sometimes spray inside the IAC with brake clean or carb clean and u may sometimes be able to free up the valves and fix the situation and be fine for a while, tho it may not be a perminate fix; however u will at least know for sure that was the problem..hope this helps u both, good luck
