In the throttle body.
As far as I know the only road speed governor would be an aftermarker unit. It can be removed but you would have to know what you're doing. The ones I've seen take the thottle cable off the thottle body and run it to the aftermarket unit. Then a new cable from the unit back to the thottle body. I guess you could hook the original cable back to the thottle body and "by-pass" the unit. Rich
Irk but it feels like it at half thottle
The tube must be pinched or bent.
It is not adjustable...... It has been pre set at the factory.
The MAPP sensor is located on the passengers side of the thottle body. Remove the "dog box" and when looking from the inside of the vehicle you should see it on the right side of the thottle body. It's kinda tricky to remove ...but it is do-able. Good Luck ... hope this helps. MR. X
right in front of the thermostat on the bottom rad hose beside the thottle body
If the vehicle is in neutral or park and it doesn't rev over half throttle, it is the rev limiter (governor). That is normal.
On the V6 acc. just connected under the thottle body.
Does it have a choke? get it fixed.
lookin at engine from the front it is located to the right above the valve cover close to the thottle body. has a wire and vacume hoses on it
have them check the codes , but prob will be the throttle position sensor is out of whack.
The thottle body is connect to the plantum right in front of the air filter housing the throttle cable is connected to it.
It's located on, but right below your thottle body with 3 screws like a sensor. You will be able to find it if you take off your stock/aftermarket Intake.
its on the back side of the thottle body on top of the intake manifold. There are some good pictures showing the location and instructions for repair/replacement at Autoclinix.com specifcally for the Crown Victoria.
This is generally the explanation when you get a PO401 check engine code. It is ussually caused when the carbon builds up in the channel leading from the EGR through and into the thottle body. Most of the time it can be fixed by cleaning the passage with a good carb cleaner and a wire pipe cleaner restoring the flow of air through the passage. Sometimes you might have the replace any one of the EGR Value, EGR Solinoid or the EGR Pressure Sensor. These can be costly, so begin with the cleaner. You may have to remove the thottle body face plate to gain better access to the channel.
Yes it could be the throttle body and this was the case with mine. Mine would be stuck when the car was not used for a day or so but otherwise worked fine. The accelterator had to be pressed hard and when it broke free, there was more than desired acceleration. I found the thottle body to be gummed up pretty bad particulaly on the down stream side. I could not clean it well without removing the thottle body. Once I had it removed, cleaning was easy with some carb cleaner and a toothbrush. Cleaning the throttle body restored normal function.
Likely, your shift linkage from the carb to the tranny has become disconnected. Or, it's designed that your engine is supposed to slow so the transmission can safely shift gears. I say just live with it. It's not causing any problems.
Idle speed incorrect , fuel filter clogged , fault in fuel system , faulty emissions system components , faulty or incorrectly gapped spark plugs , vacuum leak at the thottle body , intake manifold or vacuum hoses
try changing the cat. they plug up causing motor not to breath under thottle but will idle great....
There should be a idle set screw on your application. If not, then this is done at the factory, and covered up so you cannot reset it. I believe on a 1989 there should be a thottle ajustment. Just follow your cable from the fire wall, should take you right to it. Good luck
Wires from distributor can age and loose conductivity, especially under high voltage of full-thottle acceleration.
If you were cutting the grass with any type of lawn mower and it dies, it is most likely not a big deal. It could simply mean that you need more gas.Ê
1 spark plugs worn , fouled or not gapped properly. 2 fuel filter clogged. 3 spark plug wires faulty. 4 low or uneven cylinder compression presures. 5 vacuum leaks at the thottle body , intake manifold or vacuum hoses .
first i would change the tranny fluid and filter. if not the the thottle position sensor may be going bad.
