Car Shaking Problems
Car shaking problems are usually the results of mechanical problems. Out of adjustment tires or suspension will make the car shake after reaching a certain speed. Warped brake rotors will also make the car shake when it’s slowing down.

Why would the acceleration fluctuate?
Possible coolant sensor or O2 sensor, among other possibilities. If a sensor is bad, it will tell the computer to make an adjustment, when it does other sensors tell the computer "what's your problem, stop that." For example, say a coolant sensor is bad. The car is already hot but the sensor thinks it is still cold. When it is cold or the sensor thinks so, the sensor tells the computer to add more fuel, thus the idle increases. Now another sensor, say the oxygen sensor, says "hey your running too rich, stop it" so the computer again adjusts it, thus the decrease in idle. Depending on the type of fuel delivery system your Car/truck has. Induction will play a major role in how the engine performs. For example,Most fuel system with mass air flow induction will rely on the AIT sensor,02 sensor and air flow to the throttle body to ensure proper fuel mixture. Faulty sensors ,torn or brittle induction boot can result in acceleration fluctuation.Proper diagnostics,and inspect of engine componets will most likely expose the problem. The TPS sensor or the wiring leading to the tps sensor
What causes a engine to shake while in park?
it could be two or three diffent things that's causing the problem (1.time to change fuel filter and add a fuel system treatment and also change the air filter,the fuel filter should be changed every 30,000 miles and air filter every 3,000 miles.(2.major tuneup which consit of changing ign.cap,ign.rotor,ign.wires,sparkplugs,(3.check engine mounts.
Why does the steering wheel vibrate when braking?
You possibly have warped brake rotors on the front. Or Bad Wheel Bearings.
I'm not a big rig mechanic but I've heard this question before. A head mechanic for one of the big truck fleets said it sounds like the truck has a problem with the three-axle alignment. At 50 mph you are at the least amount of strain on the system. The rest of the time the system is above or below the correct "harmonic" to correct the vibration.
When do you know your car needs an alignment?
If the steering wheel is crooked, or car pulls one way, or you notice that the inside or outside edges of a tire is wearing more than the rest. See the related link below for wear problems to see a diagram of what to look for.
What would cause a vibrating and grinding sound on a front wheel drive van?
Bad wheel bearing or defective brake pads.
What is Warranty of OEM catalytic converters?
OEM catalytic converters have a warranty of 96 months or 80,000 miles. Inquire from a nearby auto dealer to find out where and how you can find a written warranty.
Why does your car shake when you hit the brake?
That usually happens when the front brake rotors are out of round. It is a common problem, and they can either be replaced or re-ground so that they are true again.
your wheel bearings are probobly lacking lubrication (grease),you should have it checked by a qualified technician as the bearings are liable to collapse and cause loss of control. I've had a similar problem with my 93 LeSabre at 146000 miles. The right front wheel had a bad brake hose. The hose softened up and the brake fluid remained in the calipers causing the wheel to become hot enough to cook eggs or at least burn yuour hands. The odd thing with this was the car would not pull to one side as you would expect. Once the hose was replaced the car is fine.
Which sparks plugs go in a Chevrolet Impala?
For best performance and mileage you should use the same plug that the manufacture intended for it and that is AC Delco. The parts house will tell you the proper gap.
Can you un balance driveshaft make your car shake while you are driving?
Yes, it sure can. Have your tires inspected and balanced before assuming the drive shaft is the culprit. You may also have a bent wheel.
Your problem is a warped rotor. You will need to remove the rotors and have them trued at a machine shop or replaced if they are worn too thin. It can also be a problem with your ABS system, a bad wheel bearing, or loose lug nuts. Be sure to tighten the lug nuts to the correct torque or you can warp a brand new rotor almost instantly.
Ford winstar 2001 shakes at 100km?
I have a 99 Windstar that also starts to shake at about 65mph. It also sounds like something is a bit loose on the drivers side up front. I just purchased the vehcile and was told that the tie rod end was loose and needed to replaced, not sure how much truth there is to this. I suspect there might also be something wrong with the strut. Plan on taking a closer look tomorrow because I just purchased the van this morning.
What is wrong when your steering wheel shakes uncontrolably at certain speeds?
If the steering wheel shimmy's at 55 -ish, then the front tires need balancing. Otherwise front end shake could mean something loose or worn in the front like a bad tie rod, ball joint, wheel bearing, strut/shock or cv shaft. You can jack the front end and check for play by grabbing the wheels with tires on shimmying the wheel left and right(tie rod). Up and down(ball joint) or excessive play could be the wheel bearing. Any excessive play indicates loose components.
What would cause a steering wheel and entire large car both to wobble violently?
Worn-out ball joints in the steering linkage or suspension. This allows the steering angle between the wheels to vary, causing them to wobble.
Check to see if your lug nuts are tight
Why does the car shake when it stops at a traffic light?
Hey Xiaolin=It is probalby in deed of a good tune up and just missing. Take it to a good garage. GoodluckJoe
I dont know but i once hade a similar problem and it turned out the car needed a wheel alignment
How do rear stabilizer bushes on a 2003 Ford Focus sedan work?
They're just a simple rubber bushing around the stabilizer bar and clamped into place. They allow the stabilizer bar (or swaybar or anti-sway bar as you might also call it) to pivot and bend slightly as you drive over uneven road surfaces and as you corner.
If you choose to replace them (usually because they make a clunking noise over bumps) it is easiest to do so with the endlinks disconnected. Otherwise, be exceptionally careful not to bend the clamps when installing the new bushings.
Car steering wheel shakes pulls to left?
brake caliper is sticking due to faulty caliper or rubber brake hose.
That is typically a wheel balance problem.
There is a vacuum hose between the firewall and the back of the motor, it is formed with the 2 ends different diameters. The hose collapses when it is running which causes the engine to stall. I believe this is a dealer only item. Just replaced mine and the car runs fine now.
Take it to auto zone and have the codes read for free.
its just a vacuum hose probably. mine did it before too.
Autozone will not provide enough help.
Pull the codes from the computer, match the code to the troubleshooting procedure, follow the procedure to find the source. Repair the source, light will go out if that was the only problem. There are "monitors" or self tests the computer runs the car through a drive cycle, if a problem occurs, it may not run all of the self tests until that problem is taken care. Therefore, another problem may exist. It is emission related. OR hook up a scanner that is capable of clearing codes, and hope that none are still active.
Check that the Oxygen sensors are correctly installed and working. Also check with your ford dealership to see if your car is one of many that needs a new FUEL pump. Ford has a TSB on this and will replace it for free... I have a 2003 Focus SVT with all the same problems.
could be a PCV Valve. My 01' Ford Escort with similar engine needed that recently. Appox 5 dollars easy fix.
My 2000 Focus wagon had the exact same problem and I could hear vacuum sucking in the engine compartment. In the end it was two failures at once: 1) the PCV hose failure like everyone else, and 2) a broken white plastic vacuum cap on the intake manifold.
Some folks have luck simply replacing the odd-sized PCV hose with the Ford replacement, but I was not so lucky. In my case both ends of the PCV line (under the intake manifold and connected to the PCV valve) were bust. So, to replace the entire assembly I did the following:
I bought a "PCV elbow" (by Help! auto parts), hose clamps, 3 feet of 7/16" fuel line, and a replacement PCV valve all from Pep Boys. I bought a 1/2" brass hose connector from Lowe's. I connected the elbow to the fuel line with the brass connector and secured the PCV valve in the other end of the fuel line with a hose clamp. I removed the old hoses and PCV valve and replaced them with the new rig. I had to route the new hose around the engine block, but there was plenty of room.
I still had vacuum leaking and a really rough idle after replacing the PCV line. I found the source of the leak by using a length of hose as a stethoscope. It was a rotten, white plastic cap on the intake manifold. I bought a set of rubber vacuum plugs (by Help! auto parts) from Pep Boys and one was a perfect fit.
After both of these fixes the idle was back to where it was a couple of years ago. Good luck!
the vaccume hose is broken and is over heating you need to replace it for only $500
:if nothing has helped so far, check your egr valve as it probably just needs a good cleanin'. egr stands for exhaust gas recirculation and is usually located between the exhaust manifold and the intake manifold. it gives metered, pre-heated air from the exhaust to the carburetor and generally has carbon deposits on it. it sounds like yours has an abundance of carbon in the passage causing the car to die when your approaching a stop sign or something.
