Your throttle body may be getting dirty or your throttle cable is getting clogged. You can take some wd40 and spay the cable it self. Go under the hood, find the throttle cable. You see where it's steel and then gets some plastic covering. Spray the cable there several times and work the cable in and out. The liquid will work it's way through the system. If that dosn't solve it try cleaning the throttle body. I wouldn't suggest this unless you are mechanicaly inclined. If you are, then I'ld get some carb cleaner, open the butterfly, spary cleaner in and let soak for a couple of minutes. Easiest way to clean it would be get a used tooth brush and bush gunk away. When it's down to the metal, a silverish color, it's clean. If you are still having problems, I'll need more info or go see a mechanic.

How do i set the cruise control on my 1994 mercedes c220 elegance automatic


Cruise Control
Any given speed above approximately 22 mph (35 km/h) can be maintained with the cruise control by operating the lever.
-see photo

  1. Accelerate and set: Lift lever briefly to set speed. Hold lever up to accelerate.
  2. Decelerate and set:
    Depress lever briefly to set speed. Hold lever down to decelerate.
    Normally the vehicle is accelerated to the desired speed with the accelerator. Speed is set by briefly pushing
    the lever to position 1 or 2. The accelerator can be released. The speed can be increased (e.g. for passing)
    by using the accelerator. As soon as the accelerator is released, the previously set speed will be resumed automatically. If a set speed is to be increased or decreased slightly, e.g. to adapt to the traffic flow, hold lever in position 1 or 2 until the desired speed is reached, or briefly tip the control lever in the appropriate direction for increases or decreases in 0.6 mph (1 km/h) increments. When the lever is released, the newly set speed remains.
  3. Canceling
To cancel the cruise control, briefly push lever to position 3.
When you step on the brake or the vehicle speed drops below approx. 22 rnph (35 km/h), for example when driving upgrade, the cruise control will be canceled.
4. Resume
If the lever is briefly pushed to position 4 when driving at a speed exceeding approx. 22 mph (35 km/h), the vehicle resumes the speed which was set prior to the cancellation of the cruise control. The last memorized speed is canceled when the key in the steering lock is turned to position 1 or 0.
Note:
If the engine does not brake the vehicle sufficiently while driving on a downgrade, the speed you set on the cruise control may be exceeded and you may have to step on the brake pedal to slow down.
As soon as the grade eases, the cruise controlled speed will again be maintained as long as the brakes were not previously applied, or the lever may be used to resume the previously set speed if the brakes were applied.

What's your problem?my 96 blazer is revving at about 3100 in park and neutral and accelerates on its own to about 40 45 mph anyone know why this is happening?


You have a stuck/defective IAC(idle air control) motor or a HUGE vaccum leak.Or,your throttle cable could be binding,causing the throttle to stick.

Question to Toyota Ed: How would you explain Toyotas with Sudden unintended acceleration in cars that have the Denso pedal in them? I have heard that Volkswagen Jettas are also using the Electronic...


Hello, Zman777.

According to the material provided by Toyota, the Denso pedal does not have the alleged acceleration issue.

Also, according to information that has been provided by Toyota, the alleged acceleration issues is being caused by two possibilities;

One is additional placement(s) of floor mats on top of the factory floor mat. The extra mats are not secured, and can move around the driver side footwell, and, in the worst case scenario, move on top of the accelerator pedal, and trap in into the 'applied' position. I myself have experienced this mat/entrapment issue during a road test.

The other possibility is that certain accelerator pedal mechanisms may mechanically stick in a partially depressed position or slowly return to the idle position. Over time, the internal mechanism in the accelerator pedal my become worn. As a result of this wear, combined with certain operating and enviromental conditions, friction in the mechanism may increase and intermittantly result in the accelerator pedal being hard to depress and/or slow to return or, in the worst case, stick in a partially open position, increasing the risk of a crash.

In short, according to what we have been provided, the issue is mechanical, not electrical. The modification that Toyota dealerships are performing rectify this issue, and, this modification has been approved by the NHTSA.

Nowhere has it been found that the vehicles with the alleged acceleration issue have 'accelerated' without warning, as in sitting still, and the car is suddenly going 100 mph. None.

What 'could' happen, if the pedal 'was' sticking, is, in my opinion, an 'Unexpected Non-Deceleration' condition.

If you were going 15 mph, and the alleged issue appeared, when you let off of the gas pedal, the car would continue at 15 mph, and NOT accelerate to 100 mph, as has been falsely mentioned in the media.

Regarding VW, sorry, I cannot comment on VW, or any of their systems, I am not a certified VW mechanic.

I hope that this info helps you out.

I would really have that exhaust checked again, as well as have mechanic put fuel pressure gauge on & drive it up to that speed and see what happens fuel pressure wise. With exhaust, it's not only cat converter that could be causing reduced flow.
