Question about 2004 Ford Explorer

Gas pedal slow to respond

As I apply pressure to my gas pedal nothing happens right away and then all of a sudden the car lunges forward as if I goosed the pedal. It only acts up at take off. When hauling a trailer it seems that there is enough weight behind me to offset the lunging forward. I had the software replaced with little to no improvement.

    The car does not have a Carb and it is not the fuel pump. I had the pump checked when I had the fuel filter replaced. This car has a "drive by wire" system. I am trying to find out if the start point for the sensor is right and how should it be set. Any ideas along these lines?

Let me base this one on personal experience.

i had the exact the issue with a Lynx Ghia m/t after cleaning some parts under the hood. at first i thought it has something to do with the engine itself, compressing gas and blowing it like crazy, then i took it to a mechanic. to my surprise, i extended the clutch so even if i dont do clutch the car is in clutch, then when it slips, the car lunges forward.

just want to share it, you may check that out too, consult the owners manual on proper settings.

you can treat this one a solution or not thats okay, i just want to share my experience.

Hi,
The problem in your case could be with the Electronic Throttle response mechanism.There is an (18-28) switch that can cause this problem.

Thanks

Engine noise and rpms going down


Does the engine light come on during this failure? If it does, please have the codes read and forward them back to me. From your symptoms, it sounds like a mechanical failure. I would inspect the TAC (throttle actuating control) valve. and the throttle pedal, to start? You can look at it physically, inspect the wiring, condition, and operation. If you can get a friend to help. remove the air inlet tube, look at the butterfly inside the TAC unit. Have your friend turn the ignition key to run (DO NOT START THE ENGINE) and watch the butterfly respond as he or she applies and releases the throttle pedal(request to your helper, to communicate how far the pedal is going down and coming back). The motion of the pedal and the butterfly should be smooth and consistent. Would you tell me how often these symptoms occur and does it happen when the engine is cold, hot, or any temperature. Write back with any additional information or questions, good luck.

2003 Murano will not respond when you step on the gas pedal for 4-5 seconds and then lunges forward quickly.


Hello
The engine and transmission in this cars drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL THE DIAGNOSIS & TESTING IS COMPLETED.

I have a 1997 dodge avenger es 2.5 liter here's


Check the vacuum line on the fuel pressure regulator for any sign of gas being sucked into the line. A failed regulator will let extra gas get into the engine. If it's okay, have the fuel pressure checked. That's sure a lot of gas, way too much for the engine. Good luck.

This happened to me and we couldn't figure it out. We ended up changing the spark plugs and all that and then it started working perfectly!

Gas pedal unresponsive


Try this: Go to your local parts store and purchase a can of (throttle body cleaner) you will take your air filter out and remove the big tubing that is connected to your throttle body and filter housing. Spray the cleaner inside the throttle body, open the (butterfly) and spray around the pivot the butterfly opens and close on. What happens is you get carbon build up in these areas and it causes the gas pedal to feel like it's stuck and have to apply more pressure to the pedal. You will see alot of black carbon run out of the throttle body. Take a clean rag and wipe down the area of the throotle body. Repeat the cleaning 1-2 times. put your air inlet tubing back on and re-install your filter. It may seem hard to start at first but it's drying out the cleaner that was sprayed inside the body. Try this and see if this works. I've done this on many vehicles that shops want to charge $300 to do and all you need is $5 cleaner. It's very easy to do and takes 20 min.

Accelerator got stuck while passing a truck.


When you passed the truck... I guess you couldn't tell if the pedal was stuck since you were focused on braking.

When you brake, your brakes will overcome the acceleration of the car causing it to slow down, but like you describe, the second you let go of your brake, your car accelerates again.

It would sound like either the throttle pedal (gas pedal), the throttle line (connects pedal to throttle assembly) or your throttle assembly (on the engine) may be sticking....

Engine suddenly revs when stopped & @ idling


sounds like one of the metal arms connected to the engine may be getting stuck some how. have someone get in car and press on gas when car is off while you watch engine to see what is moving, then check those arms to see if there is any possible obstructions or knicks or something on them
