1994 explorer 4.0L engine racing

My 1994 explorer 4.0L engine automatic is racing. I replaced the throttle cable but it was only marginally better and it still gets up to 2500rpm in park and neutral. I noticed that the "throttle body" (where the cables connect to the air intake) seems loose and the stop that has an adjusting screw stays about a 1/4 of an inch away from the stop, that is, it never touches the stop. I don't know if this detail helps but would give me some direction to solving this problem.

SOURCE: HELP!! 1994 buick parkavenue Will not stay running

Hi..
Are a lot of parts that give this problem or similar on your vehicle.
I will mention a few of them.

1--- Check the FUEL PRESSURE.
2--- Check the COIL PACK. And each induvidual coils.
3-- Check compression on all the cylinders.
4-- Inspect and check the MAFF sensor.
5--- Check the CRANK POSITION SENSOR.
6-- check the CAM POSITION SENSOR.
7-- Spark PLUGS and Wires.

OK. I hope this can be a initial step to diagnostic your vehicle

Thank you for use fixya..

SOURCE: Jag XJ6 revs are too high

If you have replaced the Throttle postion sensor (TPS) or have replaced the battery, sometimes the car will need an engine set up.
I had the same problem with my xj6 and I did an engine set-up and it has been fine for the last 2 years. Also with the idle doing what it did it had a very harsh shift when driving and changing gears.
The BAD news is the dealer has to perform the engine set-up using the WDS (worldwide diagnostic system) The set-up will set the kick down switch, it will calibrate and set the TPS and also perform an oxygen sensor orientation test.
With the set-up it will allow the TPS sensor to be adjusted to the correct factory specs.
Sorry you can't do this your self.
This is obviously if there is no vac leaks and the throttle butterfly is set to 2 thousands of an inch. (gap on the side when closed throttle) check with a feeler guage.

SOURCE: 1989 Cavalier Z24 Stalling problem

Have you heard of Noid lights? You unplug the fuel injector and plug these in and they will light up if the injector is getting power. This might give you a better hint. There are also lights that go inbetween the spark plug and wire. Between these two items you may be able to narrow down the problem to a specific system. I believe that your car has a coil pack. Some of these engines have problems with the crank trigger. I believe it is located on the back side of the motor. If you decide to change it, be careful. I have heard of them breaking into two pieces and becoming a big problem.

SOURCE: 98 Nissan Maxima Have replaced plugs, mass air flow sensor, cleaned throttle body, adjusted TPS and car still stalls at stop lights, have to put in neutral so it won't die. I can have the vehicle

The EGR Valve is either stopped up with carbon or it is justed worn out.More than likely there's carbon stopping air flow.You can try cleaning it with a non-chlronated brake cleaner and a scraper or wire brush.Reset the computer.

Where is 1994 Sportvan downshift relay location


There's no such thing as a downshift relay.Trans downshift is cable actuated.Go to the end of cable at the carb/throttle body,open the throttle fully by hand and depress the black button in the cable connection block,the cable housing will pop and when your driving will automatically reset to where it needs to be.Your done.

Gas pedal gets stuck and keeps the car going cant stop without turning the car off


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.

2005 Ford Explorer V6 goes into fail safe mode with wrench


It should be noted that the ETC system includes a warning indicator (wrench light) on the instrument cluster that illuminates when a fault is detected. Faults are accompanied by DTCs and may also illuminate the malfunction indicator lamp (MIL).
Torque Based Electronic Throttle Control (ETC)
Overview
The Generation II (Gen II) torque based electronic throttle control (ETC) is a hardware and software strategy that delivers an engine output torque (via throttle angle) based on driver demand (pedal position). It uses an electronic throttle body, the PCM, and an accelerator pedal assembly to control the throttle opening and engine torque. The ETC system replaces the standard cable operated accelerator pedal, idle air control (IAC) valve, 3-wire throttle position sensor (TPS), and mechanical throttle body.
Torque based ETC enables aggressive automatic transmission shift schedules (earlier upshifts and later downshifts). This is possible by adjusting the throttle angle to achieve the same wheel torque during shifts, and by calculating this desired torque, the system prevents engine lugging (low RPM and low manifold vacuum) while still delivering the performance and torque requested by the driver. It also enables many fuel economy/emission improvement technologies such as variable cam timing (VCT) (deliver same torque during transitions).
Torque based ETC also results in less intrusive vehicle and engine speed limiting, along with smoother traction control.
Other benefits of ETC are:
  • Eliminate cruise control actuators.
  • Eliminate idle air control (IAC) valve.
  • Better airflow range.
  • Packaging (no cable).
  • More responsive powertrain at altitude and improved shift quality.
  • DO you know what electronic throttle control is ?

My 1999 Ford Explorer has the ABS and Engine light lit. When I put on the scanner, detected errors with the following codes: C1230, P0171 and P0174. What problem does my ford explorer?


You will need a book for that...and good luck at finding what you need, the Chilton Books, and others have cut their info. back to maintenance only...for the most part. go to AutoZone, They have a good system, and if you find a friendly Parts Person, they might be able to help you...or you can take it to a known, good, Mechanic...

Engine Racing


It may be the cruise control cable - I had a vehicle do this to me before. The engine raced as soon as I started it, even in park. A couple of times, it stopped racing - then I pressed the gas pedal, and the RPMs did not drop when I released the pedal.
If it acts somewhat like that, check under the hood and find the cruise control system - it is most likely a 3-4" diameter, 5-6" long cylinder-like object mounted on top of the engine with a long cable coming out of it going toward the back of the engine. Check all of the clips on the cable and make sure they are intact, then make sure the cable is fully attached to the throttle body at the end. My cable came loose and got itself wedged in the throttle body, preventing the throttle from closing.
If the cable seems fine, check for other obstructions on the throttle body - there may be something else holding it. It may help to have somebody inside the car pressing and releasing the gas pedal (engine off), so you can see whether it fully opens and closes.
