Where and how do I adjust the throttle / idle ? My

Normal idle speeds on modern cars are usually between 600 and 1000 rpm so the idle does not seem too fast. Most modern cars now use electronically controlled throttle bodies instead of carburettors and most throttle bodies are not adjustable.
The idle speed can run higher when the engine is cold as more fuel is added until it reaches working temperature. Let the car warm up to it's working temperature, usually about 10 minutes at idle.
Keep your feet off the pedals and check the idle speed. Listen to the engine. Does it sound like it is 'racing' like your using the accelerator pedal or is it struggling and almost stalling? If it is an even steady idle it is probably set correctly. Get a good mechanic to look at it if your worried.

Try cleaning the throttle valve and the idle speed control air bypass valve. Only use throttle valve spray cleaner and harsh abrasives, soak them and clean with the throttle valve with a soft cloth. Soak the idle speed control valve for an hour and then blow it out with compressed air.

Make sure no hoses came undone...and u can try a idle relearn procedure to start off with..may b coincedental that something may have went out of sack w hits

Remove air filter, warm up engine, plug the IAC port (the small hole in the bottom of throttle body) the adjust idle screw c/wise or anti c/wise to set rpm. REMOVE IAC plug and check the performance. Good luck.

dont drive it. find the cause and fix it now.
Hot and cold engine or BOTH>?
1995 Tracker, no tranny , no 4wd , on engine options stated.
Exact high RPM in neutral, not stated...... 1500 is normal cold.
keeps going in Neutral. (nah , you have 5 ways to stop any car.
key, hand brake, foot brake and neutral. and with 4wd, 1 more neutral.
keep that in mind driving any car.
this car has up to 3 throttle cables that can stick. and more!

1: floor mats hit the pedal>? ala. Toyota style (lawsuits)
2: the three cables are, throttle. , cruise and A/T transmission kick down cable. if car is M/T and no cruise it has 1 cable.
so disconnect it, throttle fixed? (disconn,. 1 by 1, bingo?

no cure?, then its not the pedal , you meant just high idle.
yes, replace the cable or bad parts three.
ok say its not the cables.. (tests proved that)
the 95 came with 2 engines, 8valves and 16valves,
they work differently (8v love so race, 16v loves to stall)

1: ISC Stuck open, common.
2: 8v, any air leaks at all , will cause super high idle speeds.
3: throttle valve in the throttle body is stuckopen (gunk) or the return spring broken (very very rare the latter,in fact never heard of one breaking)
4: IAC (thermal idle control stuck open ,(my 97 was). and lots more.
5: on the 16v it takes 2 failures. to make high idle.
gross rich running engine (cold engine its normal) and any air leak
once hot the engine can not race unless there is huge overfueling
and an air leak.
6: the 8v has this device on the side of the throttle body.
called a dash pot. its just a fast idle vacuum servo.
if stuck open the engine will scream full time....
7: ECU stuck in limphome, can cause too high idle speeds.

we need to know which engine
http://www.fixkick.com/find-parts.html
8v or 16v first.
then does the idle race hot or cold or both (engine temperatures)
if it races , then how fast?, RPM the dash tachometer tells you that.

it can be as simple as a 50cent hose cracked.
to a dead ISC. (idle speed control) IAC is thermal idle air controller.
the IAC must be closed on a hot engine,
if the the engine never gets hot,it will scream full time.

Maybe a sticking choke or binding throttle linkage. Have you lifted the aircleaner cover and looked down carb opening? Choke stuck?
Could be a simple idle speed adjustment also. What rpm's do consider to be high. Maybe some carb cleaner down the barrels and throttle linkage could free it up. Again, it could be a simple idle adjustment depending on RPM's it's turning.

If your vehicle has a throttle body control switch/valve it might be loose or defective. Also, one of your fusible links might be in need of replacing.

clean the small breath hole in the intake at the bottom.

Sticking throttle plate maybe , clean with carb. cleaner .

ignition switch broke or the car is dieseling the idle speed is too high throttle valve stuck open or the valves and heads full of carbon build up.causing preignition.
