Question about Ford Explorer
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.

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.

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.
