SOURCE: 1996 Crown Vic, Valve noise under heavy acceleration

No use what's in there, but have the engine de-carboned by a Ford dealer, or remove the octane adjust shorting bar located near the ignition module (retards timing 2 degrees), this will in most cases cure the issue unless there is allot of carbon in the cylinders. There are also methods of ing this de-carbon procedure at home, check on the internet for tips.

PLEASE RATE THIS SOLUTION

SOURCE: no acceleration

I had the same problem with one exception. It would rev higher than 3500 but the higher it revved the more it bogged. I had the catalytic converter replaced. I thought I bought a new car. Acceleration is just like new. It was easy enough to test. My mechanic cut a hole in the exhaust pipe in front of the catalytic converter. It sounded like a truck but the acceleration difference was immediate. Easy diagnosis.

The car is hard to shift because the more you press on the accelerator the more the computer for the transmission won't let it shift. Which in turn causes the car to bog more sending more unburned fuel into the catalytic converter. Which in turn causes more carbon build up and more back pressure. Vicious cycle. It will only get worse.

My thermostat caused the entire problem. Thermostat was stuck open, engine never got to operating temp most days. Car burned rich. Bad gas mileage. A lot of unspent fuel being dumped into the converter. Probably have some underlying cause that needs to be addressed. Bad plugs, wires, coil, fuel filter.

SOURCE: high idle will not lower

sounds like you have something blocking the linkage or the throttle body isn't closing totally or you have a air leak.

I'd like to get step to step instructions on how to clean the throttle body in my 2010 Jeep Patriot


  1. Purchase "02 Sensor Safe" throttle body cleaner spray;
  2. Drive the vehicle a few miles, bringing it to full operating temperature, then park it in your driveway with the engine still running;
  3. Gain access to the throttle body, and hold your thumb on the butterfly linkage so that you can open the throttle butterfly when the engine begins to load;
  4. Begin by spraying throttle body cleaner spray on all linkages around the throttle body. If the engine begins to bog because it is aspirating throttle body cleaner, quickly open the throttle butterfly to keep the engine running.
  5. Once you have cleaned all around the throttle body, spray cleaner DIRECTLY INTO THE THROTTLE BODY, opening the throttle sufficiently to keep the engine running. It will run rough during this process but try not to let the engine stall.
  6. If the engine stalls, restart it, and continue cleaning the throttle throat until you see clean metal.
  7. Pour some fuel system cleaner into the gas tank and drive the car a little more before parking it. Try to find an excuse to accelerate hard, WIDE OPEN THROTTLE momentarily if safely possible (as when accelerating to merge into traffic on a highway).
  8. Drive back home.
  9. Done.

Take the idle air control valve off and clean the carbon out of it then reset the computer by disconnecting the ground cable on the battery for 30 seconds then start the engine.If the problem still exists then replace the throttle position sensor and reset the computer again afterwards.

P1193 error code car wants to stall when stopping and accelerating


P1193 = Detected engine speed below 470 RPM. There are several possible causes/components which can contribute to this drivability issue. ELECTRONIC THROTTLE SYSTEM (ETS). In most cases, an ETS related DTC will set in pairs of codes. The first code denotes the related system or component. The second code is for the specific fault detected.
There was also probably P1191 - limp home

For this issue, on frequent occations I've found the throttle position sensor (TPS) (potentiometer) had bad spots in it and subsequently sending erratice signals to the ETS Control Module (additionally, the throttle body and plate had carbon buildup inteferring with the intake air flow. Also check for air leaks (intake air hoses, vacuum lines & tubes for cracks/leaking). Clean the throttle body & plate. Bench test the TPS. You also have an APS (Accelerator Position Sensor) located on the RH side engine compartment near the firwall next to the strut tower. These are the initial components to check/examine. Replace as needed.

1995 camaro- the gas pedal is hard to depress when starting from a stop. i believe the problem is the accelerator cable but not sure


Hi

1) If the gas pedal is hard to compress you could have a broken spring inside the throttle housing. The throttle housing is located in the sealed compartment of the cruise control housing.(The housing with the rubber bladder.) You will have to remove the rubber covering to inspect the inner workings of the throttle mechanism. If every thing looks intact push on the accelerator. If it is still hard to push in, you could have a rusty cable.

2) A simple can of WD-40 should be applied lightly to the inner workings of the housing parts.
Try the throttle again and if it is still hard to push, check the connections of the cables to the throttle apparatus. Use the long plastic tube on the spray nozzle of your WD-40 can to shoot lubricant in to the small openings of the cable sleeve.

3) It may take a few minutes of manipulating the throttle to loosen up the corroded cable connections. Once the cable slides and the throttle seems to move freely take a dab of Vaseline and coat the ends of the cable connections. Vaseline will keep the moving parts lubricated and protect the connections from becoming more corroded.

4) By lubricating all moving linkages, you can prevent further throttle sticking. Make sure you replace all coverings back to the way they were when you started. Sit in the drivers seat and push the throttle pedal a few times to ensure that the throttle is no longer sticking.

5) Take your car out for a short spin in a unpopulated area such as a empty parking lot. Start and stop the vehicle numerous times to check it out. If the gas sticks at a slow operating speed, you can simply put the car in to neutral, apply the brakes and switch the ignition off. It is always better to be safe ..

However for an easy solution check cable to throttle body, it may be kinked. This is a common problem. Remove the throttle body and clean the throttle plate with a throttle body cleaner. Clean the front and back of the plate. Just spray and wipe off with a rag. Do not scrub with a wire brush. Doing this can damage the throttle plate. You can buy throttle body cleaner at most parts stores. Make sure you clean up your IAC valve while its off, that thing gets gunked up bad after a while.

Car accelerator does not respond when constantly stopping and accelarating during traffic to a point that it starts vibrating and sometimes turns off. I have to restart the car for it to accelerate...


Any check engine light? I would suspect the throttle body position sensor, or the throttle body itself could be throwing the wrong reading back to the computer / ECU... if its not that, it could be fuel related.
