In order for your accelerator pedal to actually work as you push down on it, it needs to be connected to the throttle. In older model vehicles there was a mechanical link...
The addition of the fluids is just mere coincidence and has nothing to do with the issue. If you request a diagnostic, the first thing a mechanic would do is check for any stored diagnostic trouble codes. If there are...
Hello, thank you for writing in. The first possibility that comes to mind is the air intake sensors. Start by making sure idle air control valve, throttle, and EGR systems are all working well. These types of components can be...
Slow acceleration has a variety of causes. Fuel injectors can become clogged over time as the tiny passages become clogged. When an injector is clogged it can degrade the performance of the vehicle and the car may accelerate slowly or...
Hello, thank you for writing in. The vehicle needs to be inspected for several issues. First, the gas pedal controls the air flow into the engine, and the computer matches the amount of air to the amount of fuel needed....
Hi there. This can be caused by a number of different things. It could be because the vehicle is in limp mode or because there is an issue with a sensor or the throttle body. I would usually scan the...
Check the engine for a misfire. Check the spark plugs and see if they are working and if there is park to the spark plugs. If the spark plugs are clean and there is spark to the spark plugs, then...
Hello. It sounds like you have a failing cv axle. When the axle joint fails and has excessive freeplay then this noise will occur. It can also be caused by something loose in the brakes or possibly a failing suspension...
The gas pedal is broken in your car. I recommend replacing the gas pedal and the throttle pedal position sensor on the gas pedal if the new pedal does not come with a new sensor. The gas pedal has a...
For the cylinder that has excessive oil in it, the oil is either coming in for the piston rings being worn or the valve guide is leaking on the intake valve causing the engine to consume the oil. If the...
You may need to have you crankshaft position sensor relearned or have the sensor replaced. Also the catalytic converter could be partially clogged. If everything is working properly, then it is possible that some intake bolts could have...
If the noise suddenly appears at 50 mph, then check the brake system as there could be an issue with the brake pads rubbing the rotors. If the noise starts off quiet and gets louder with speed, then check the...
If the rate of acceleration is greater than commanded (aka, "unintended acceleration"), you might have a problem in the electronic throttle control, throttle position sensor, idle air control, or related systems. You might take a look at the OBD-II system...
Hello, thank you for writing in. The engine is likely sensing an issue and compensating for it. When you restart the vehicle, the component may be passing its start up tests, and the engine stops trying to outperform itself. Start...
Hi there. This sounds like the tires on the front are out of balance and the ball joints are worn and need replaced. A out of balance wheel will cause the vehicle to vibrate and may change location to the...
Hello - your Taurus has a Recall (#98V204000) against the cruise control, which can cause unintended acceleration. In a related later issue, new Taurus models had problems with twisted accelerator cables - again, from the cruise control, which may have...
Hi there. There is an issue with the engine having a vacuum leak and the may be cruise control is coming on to accelerate the engine. First check for any vacuum leaks on the engine. If the engine is running...
Check your suspension on your front of the vehicle. It seems that the control arm bushings are worn or damaged and the bolts could be loose causing the suspension to move around when the vehicle is under a load. If...
Hi there. The noise could be from the lifters not filling up with engine oil until the engine is warm or the pistons have too much clearance causing a condition called "piston slap". Check to see what brand of engine...
It's possible you have an exhaust restriction due to a plugged catalytic converter. To check that you could either measure exhaust back pressure and/or intake vacuum (latter gives only indirect indication of a restriction though). Among the other common possibilities...
Hi there. This sounds like the gas pedal position sensor or the throttle body position sensor is not working properly. You can try manually resetting the gas pedal position sensor. To do this, perform the following: Turn on the...
