Clean the carbeurator and lube the throttle cable.
will the transmission causes my 1999 ford expedition to bog down & sputter when accelerating the 4.6liter engine.
Your throttle is sticking open. I had an incident many years ago. I took foot off throttle which let the engine slow down, put foot on brake, the engine didn't speed up but the car did, very strange and was told impossible.
Try locating and testing or changing the TPS (Throttle Position Sensor) Or if it's not in gear it could be the rev limiter keepin you from over revving & blowing your engine.
The throttle position sensor is on the throttle body. That's the part of the engine that controls the amount of air allowed into the engine. To find the throttle body, follow the air intake routing toward the engine. The throttle body is the part that sits on the intake manifold. To find the throttle position sensor, follow the throttle cable to the throttle body. If it helps, have someone press down and release the throttle pedal while you're looking for the throttle body/position sensor. The throttle cable causes a shaft to turn, that's the part that controls the air coming into the engine. The throttle position sensor is connected to that shaft.
It is located on the top of the engine, below the throttle. Get a light and look straight down between the two throttle cables "if it has cruise control". It is bolted down with one 12mm bolt.
The governor spring adjustments
The thing that looks like a carburetor on the top of your engine, Is called a Throttle body, If you look down in it you will see 2 injectors, 1 on each side of it.
If the engine is revving up, then the transmission is having problems. If the engine is not revving, then check the linkage from the accelerator to the throttle body.
I had the same problem and it is your oxygen sensor.
A broken or maladjusted IAC valve.
A throttle positioning sensor reads your throttle body to see how much your pressing the gas basicly. So if its bad the engine runs up and down not knowing exactly how much peddle is being pushed.
It should be on the drivers side front of the engine. Follow your fuel line from the throttle body forward and down.
It could be watered down gas. It could be watered down gas. It could be watered down gas.
could be your air sensor that's connected to your intake or your throttle positioning sensor
My 1997 Neon had the same problem. I took a small nut and used silicone to attach it under the throttle. Basically giving the engine more gas. The problems stems from bad valve springs.......I have loved my neon and plan to put in a new engine in a year! Second opinion: Take it to an Auto Parts store and ask them to check and clear the codes for you, this is a free service. Most likely it is the mass air flow sensor or TPS throttle position sensor. The codes will narrow it down.
"Part Load" is short for partial load. "Load" is when the engine is doing work. Whatever work the engine is doing places a "load" on the engine which resists the engine's turning motion and slows the engine down so it requires more throttle to maintain speed. "Partial load" is when the engine is doing work that would stall the engine at idle, but does not require full throttle, just partial throttle. A good example would be a car traveling at highway speed or up a slight grade.
It could be the throttle position sensor or the idle air control valve.
idle speed motor on the throttle body.
unplug t,p,s, switch on rt. side of throttle body
t.p.s throttle position sensor
Need to know what year, engine size and if it has a carburetor or throttle body injection (TBI).
look under the hood and rev. your engine the piece that moves is the throttle on the throttle there is a wire you need to take the wire and move it back so there is more wire exposed just grab the wire with a clamp and move the throttle up and you should be fine.
Shut the throttle. Pull in your clutch. Kick the gear lever down. Let out the clutch. More advanced: Shut the throttle. Pull in your clutch. Kick the gear lever down. Blip the throttle - let out the clutch.
Your car's engine is essentially a giant air pump, combusting a mixture of fuel and air with a carefully timed spark. The more air the engine has available, the more horsepower it can make. An engine that breathes more easily will also show improvements in throttle response. Throttle response is measured by the amount of delay or hesitation that your car exhibits between when you press down on the gas pedal and when the engine responds by delivering power. Improvements in throttle response give you more "pep" in your car's acceleration.
