I need a diagram showing how the kick down cable (high idle cable) connects to the engine.

check hoses for vacuum leaks also throttle body may need to be cleaned and or throttle body position sensor can be starting to be faulty or may require cleaning with throttle body --the following links show how to clean a throttle body look up the ones that do it in /on vehicle you dont have to remove it from vehicle
How to Clean throttle body GM 3800 throttle Body Tune Up Cable accelerator... Throttle body cleaning and idle relearn procedure

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.

Have it looked at by a dealer,iam not sure here but i think you have a vacumn leak like the feed pipe to the servo split but really you need a mechanic who works on these cars day in day out and they will go straight too the problem for you

Throttle cable should pull a SPRING, which pulls the governor, which pushes/pulls the carburetor butterfly valve.

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.

The PCM (power control Unit) controls the idle speed base in input from various sensors, one of them it's the coolant temp sensor, this sensor may be telling the computer that the engine it''s too cold and the computer will keep the idle up to help the engine warm up faster

You don't say if the engine is carb or fuel injected.
If it has a carb, it could be sticking linkage for the fast idle to the choke.
If it is fuel injected it could be a faulty idle air control valve.
Or it could be something holding the throttle open like a binding cable.

Sound like you could have a defective ISC (idle speed control) sensor.

try turning down the idle via the idle adjust set screw (usually on the carburetor base). if the problem persists after the engine is warmed up, there may be an issue with the automatic choke. also check the throttle linkage by disconnecting it to see if it is holding the throttle open when connected. if this is the case, you may need to adjust it or find a slightly longer cable.

Sounds like the kick down cable is not working properly. The kick down cable is the cable that tells the transmission to down shift depending on the throttle position. If the cable fails then when the car is turned off and restarted it is in too high of a gear to go and bogs the engine till it dies. Check this out and see if this doesn't get you back in business. Hope this helps. Good luck. cj2176.
