Question about 1998 Mercury Mystique

1 Answer

2.0l, 4 cylinder. Car [briefly] stumbles upon acceleration, especially at lower speeds or from a start or recent stop [e.g., slowing down for a turn]. If you ease up on the gas, the stumble lessens and once it gets a little speed [10-15 mph], the stumble ceases. It may do it at higher speeds, but I'm not an aggressive driver, so I do not notice it. The timing belt was replaced a while ago, but I did not own/drive the car before changing the belt. Also, mpg is mediocre, maybe 20-25 on the highway. No where near the 24/35 advertised by Ford.

You will need to replace the oxygen sensor. This is the reason your vehicle stumbles upon acceleration and the fact you are losing gas mileage

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.

98 Corolla stalls or stumbles when cold


It sounds like you may have picked up some small debris from the bottom of the gas tank when you ran it empty. You may need to run a fuel/injector cleaning solution through the next tank of gas to clear the debris and consider changing your fuel filter too. Sea Foam is a great fuel additive and I recomment trying it full strength. Hope this helps!

I Have A 93 Ford Escort Lx Im Having A Problem Accelerating After Driving It For About Ten Minutes I Will Drive It For A Little Then When I Come To A Stop Light It Sputters And Jumps Around And Sometimes...


By the sounds of it, its like once your car gets hot its starts playing up. You should run a compression test on all ur cylinders..you can get a tester from your local automotive store quite cheap, you just screw it in or shove it in and hold it, start the car and use the throttle cable hinge to rev the car slowly up to redline.. do that while the engine is quite hot though to get a more accurate reading, especially because i think thats when your car starts playing up (when its hot) im just going to say it should be around 140 for all cylinders.. just double check that and cross check your readings with ford. It also could be a ECU problem, once your car is running hot (normal temp) the tuning is wrong.
