Car Shaking Problems

may be due to out of balanced wheels, simply you do wheel balancing. Or otherwise worn out tyre

i dont speak car!

If the light is flashing there is SOME kind of code in the computer. It may be an ABS code, a transmission code or who knows what.

Unfortunately you'll need to find out what it means and engine diagnostic scanners don't always tell the whole story.

try adding transmission fluid and trans treatment if possible. If it is shaking while you are moving then your rims can be bend or your alignment is off.

the air conditioner kicking on and off will do it too/;p

You have a broken serpentine belt. Replace it.

Your engine may be misfiring. Check your fuel and ignition systems. Another possibility is that you have a worn engine mount that is allowing horizontal movement of the engine.

Most likely, yes.

Because your wheels would have been aligned to when they weren't balanced. Now that they are, they are likely misaligned.

Hope this helps.

If it is vibrating at speed you have either a tire out of balance, bent wheel, defective tire with broken belt, loose wheel, defective wheel bearing, bent driveshaft, or bad CV joint. If it is vibrating at idle or slow speed, you have either a cylinder miss, broken motor mount, or vacuum leak.

sounds like your break rotors could be warped.

You may have a wheel balance problem or something wrong with the suspension or steering gear. Take to a shop for check NOW, this is serious.

1 - simplest and cheapest method- replace the axle

2- replace the CV joints and boots

3- lots of unnecessary work, very expensive - check the joints and replace as needed, replace boots

A flat tire is one possibility

For cars that are older, there's a possibility it is cause by poor idling adjustment. Older car have carburettors, that would allow the adjustment of idling speed ( And the CO and CO2 mixtures).

For most modern cars, most are EFI( Electronic Fuel Injection ) that are control by ECU. Perhaps, in order to eliminate this problem, probably should have the mechanics to check if there could be any fault(s) to be found in the various sensors, such as; Throttle Position Sensor (Electronic control system is hunting (up and down) for the correct air/fuel mixture, and the engine would not respond to throttle input but to input by electronic sensors) and O2 sensor( ECU is constantly altering the injector pulse width, measured in the exhaust by an O2 sensor, in its search for the perfect air/fuel ratio).

Above may not be the complete solution to solve the above problem, hope it help in its little way.

Another idea is that the engine is missing (not firing or not firing correctly) on one or more cylinders while at idle; whereas an increase in engine RPM makes the missing unnoticeable...or to disappear (in the case of a mixture being compressed enough to ignite or ignite more efficiently before having time to decompress via leakage).

Possible reasons for the above might be:

1) Dirty/fouled spark plug(s) that need cleaning/replacing. (Broken and/or worn valve stem seals can cause the respective spark plugs to foul).

2) Burnt valve(s)...(from age, too high of a combustion temperature, inaccurate timing, or using unleaded in an older auto that requires leaded gasoline)

3) Blown head gasket. (Coolant entering cylinder(s) can cause non-combustion at low RPM, and not at higher RPM or non-combustion is not noticeable at higher RPM) (And/or compression loss via blown gasket passage causing non-combustion).

4) Cracked cylinder head. (Missing caused by same process as in #3 above except through passage of the head crack).

5) Cracked piston. (More unlikely).

Hopefully this has helped in giving some more insight. Vullin

Check your motor mounts. Have a friend eye the motor when parked. Apply the brake, put into drive gear, hold the brake and lightly press the gas. Try the same in reverse and watch for excessive twist in the motor.

There are a number of things that I know of that can cause this one. First off did you have an alignment done after replacing the tires? I would also suggest checking out your front end ie ball joints, tie rod ends, wheel bearings and so on. Good luck

If you have not had a balance and rotation on your tires within one year, this can cause shaking of your vehicle. Also, if you have a lift or heavy duty tires, your vehicle will be prone to shaking.

You don't. The ECU controls the ISC (Idle Speed Control Motor) which adjusts the idle. If idle is out of control (too low or too high) try gently tapping the ISC with a small (0.5 pound) hammer or a large wrench while the engine is running. If tapping the ISC makes a change in idle speed, you need a new ISC. Clean the throttle body whenever replacing the ISC.

If the ISC is not the problem, look for vacuum leaks which can cause both high and low idle. Low coolant level can cause high idle.

Also, note that many clueless drivers assume that the idle is wrong (high) when the car is just using high idle (normally) for a short time after a cold start especially in cold weather.

Bad spark plug(s), vacuum leak, dirty/failing fuel injectors... either of the first two are most likely problems to cause bad misses.

My camaro did the same thing minus the grinding and it ended up being the control arm. Although yours sounds like wheel bearings because of the grinding which can also cause vibrations.

Bent wheel, bent driveshaft, worn CV joint, or broken motor/transmission mount.

Need more info. Cupped tires will cause a roaring noise like nasty four wheel drive tires going down the road. Your can identify cupped tires usually by standing at the rear of the car and alternating, your tread blocks will look, LIGHT, DARK, LIGHT, DARK ....most of the way around the tires. Either all the way across the face of the tread, sidewall to sidewall or maybe just on the inner or outer edge of tread. Could have something stuck in tire tread? I have pulled out spark plugs, pliers, animal bones........some weird stuff over the years that make strange noises! Good Luck.

check u joints check lug nuts

I don't know, but that's what my house smells like right now, and I'm a little concerned...anyway, I would suggest cleaning out your air conditioning/heating vents, or turning the heat down. The smell may be from your heating system overheating and melting the plastic of the vents..or just from dust or other crap in there.

Faulty: spark plug, spark plug wire, ignition coil, ignition module, fuel injector are the most common. Coolant leaking into a cylinder is another.

Internal engine problems such as burnt valve, broken valve spring, bent push rod, worn rings
