Car Shaking Problems

Your ABS (Antilock Brake System) is kicking in. It's working.

If you are referring to the colored dots, they are there to help the technician when they mount the tire on the wheel. A yellow dot is supposed to be aligned with the valve stem. This makes it easier to balance the tire with the least amount of weights. The yellow dot is the lightest part of the tire. A red dot indicates a spot in the tire that is the thickest.

check u joints on driveshaft.

Mabey you are low on gas or mabey a ring of som sort for ex: Piston ring

Sadly this as it happened to me yesterday after I took my son to school!! :(


The whole of car will shake and the engine will rattle (open your bonnet and you will see it shake violently all over the place) also your engine will be very noisy, it will struggle up a hill or any slight incline and will not go over the speed of 25mph no matter how much you press the accelerator!


*REMEMBER* when replacing ignition coils make sure you replace it's pair!

for example

number 1 went so you need to replace number 4
number 2 you'll have to replace number 3

with mine number 4 went so I had to replace number 1 too and it's possible that 2 and 3 are going to follow :(


***I believe the previous answer was referring to spark plugs, not sure.
But I recently had to replace the ignition coil in my 92 Chevy Blazer. It really didn't give any signs of failure except that now and again the vehicle would shut off and take a few minutes to restart. I just bought the truck about 3 weeks ago and am still workin on it as there are a few things that are still not right, for example when i got it none of the vacuum hoses were hooked up.
Anyway, back to your question...the day my ignition coil went out and left me stranded I was lucky to have a Haynes repair manual in the truck with me. So after 30 mins of doodling under the hood I decided to check the coil pack. The Haynes manual gives a walk through for checking your ignition coil. Besides the few tools required to remove the coil you will need an ohm meter. There are 4 different test that can be performed with a meter. I was also lucky to have a meter with me and an Advance Auto a block away. $28.00 and 20 mins later, I had it reinstalled and haven't had any issues with the truck not starting.
*Tip: if you have to replace the ignition coil, and if it's like mine- the replacement will not come with a mounting bracket. You will have to reuse the one off the original. The new one will come with small bolts though. The original mounting bracket is usually fixed onto the coil pack via 2 pins that are pressed on. I simply used a sturdy screwdriver and hammer to break the head of the pins off and it will slide free.

Hope that helped.

Its on the engine side of the injection pump. 14mm lock nut and flatblade screwdriver to adjust. Do not over tighten or you can break off the mount like on this pump. Turn the bolt clockwise (right) to increase idle speed, counter-clockwise (left) to decrease idle speed. Once adjusted, re-tighten the 14mm lock nut.

I would say at least once every 3-4 months.

A clogged muffler can.

Yes. I did that, works well.

You have a "Warped" brake rotor. It needs to be replaced

Warped brake rotors will cause pulsation (or vibrations at high speeds) when the brakes are applied. This may also go on to misalign the calipers and cause other vibration related damages.

When the air conditioner comes on, which includes turning on the defroster at low temeprature ranges, it draws a lot of power from the engine. This can result in a decrease in idle speed and less available power on starting off from a start. This is often felt as a shaking or jerking. It is possible that the idle is low or that there are problems preventing full power.

yes, but it could be other problems as well. If rotor is out of round, it will vibrate, could also be a wheel imbalance or a bad wheel bearing or even uneven braking caused by a caliper issue. You will have to inspect all carefully.

The brake rotors are either warped or scored, or the pads are close to worn out. Warping can be caused by over-tightening the lug nuts or from hard stopping from high speeds which will cause the rotors to overheat and warp.

Scoring can occur as a result of natural wear and age. Pad wear can be accelerated by mechanical faults, but will eventually appear on any vehicle that's in regular use.

Note: Uneven application of braking power at high speeds, caused by the heat that is made between the rotor and the brake pad; this is causing uneven stresses in the rotor. Such heavy brake usage aggravates the situation by providing uneven wearing along the circumference of the braking surface.

You bid on it just like the salvage yards. High bidder wins the car.

Yes, it sure can.

If the timing is off a lot it can make your engine misfire and may not fire on every cylinder on every rotation. This can cause your engine to shake on its mounts and therefore shake your car, but usually at low RPM's. Poor airflow to the fuel ports can also make your car idle roughly. Might be a dirty air filter or the mass airflow sensor might be dirty (you can get throttle body cleaner for that). Also, low oil can cause you car to run roughly and labour a bit on hills.

the gears have to readjust from the stop position.

It is also possible that you have a broken motor mount and the car shakes when you hit the gas because the motor shifts position when the torque increases.

Brake rotors are warped.

1998 Toyota RAV4 headlight bulb lamp replacement procedure: Purchase the correct replacement headlight bulb(s) first, before disassembling the vehicle. See sources and related links below for replacement bulb information and full light bulb part numbers list. Then consult your owner's manual for the headlight bulb lamp replacement procedure. As simple as it sounds, the owner's manual is the best place to start for bulb replacement instructions and illustrations. You may want to consider replacing both left and right at the same time in order to keep brightness and color equal (optional).

Warped rotors is the most likely cause. Have the rotors turned or replaced and new pads installed.

When your steering becomes and loose and woolly, your steering box is normally the culprit. Over time, the cogs in the box will wear slightly and loosen from each other. There are set screws on the box to help minimize this effect without needed to buy a new box. however, the adjustment is slight without locking the steering up, so you may just need to get a new box. Also, low power steering fluid can cause this. Check your level and pump.
