Do you have a check engine light?

What did you service and did you disconnect the battery at anytime?

now the engine vibrating, some times brake is not working properly
and without accelaration rpm around 1800, car is moving faster
speedameter and rpm meter is not proportional
now the main problem is engine vibrating '
is it due to air and fuel mixing prblem?

Check the idle air control valve and look for a vacuum leak-

I recently took my car to a Quality Auto Center Because of the heavy vibration that I felt coming from the engine. I especially felt the vibration when the brake pedal was being pressed at a stop light. He replaced 2 engine mounts in the front that were not that worn and he said that would ultimately fix the problem. Two days later the vibration is back again. Could this be something wrong with the engine or should I take it to a dealer for a full diagnostic test?

Thank you

Hi there,

These engine have balance shaft set ups which go bad and cause the engine to vibrate the shaft set up in in the engine oil pan. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

When I'm stopped at a red light, there is a very low rumbling, so low, that it's hard to tell if I hear it's a noise, a vibration or both. The vibration I feel is in the brake pedal.

My mechanic added some 44K but that didn't solve it.

Thanks.

Hi cpye,

We need to understand the problem before we can assist.

Is the vibration or noise present only with the brake pedal depressed?

With gear in Park, does it happen?

With park brakes on, does it happen?

Could it be some relays flicking?

Hi,

I tried it out in my driveway where I could concentarte just on the noise. Here's what I found.

1. It doesn't start until I drive around the block to warm it up a little.
2. It's definately more of a vibration than a noise and I feel it both through the wheel and the brake pedal.
3. I feel it in Drive, whether I use the brake pedal, the parking brake, or both.
4. I don't feel it Neutral or Park, whether I use the brake pedal, the parking brake, or both.
5. I don't now what the relay is but there are no lights flickering while it happens.
6. I also checked it with the fan and A/C on and off, and both are the same.

Thanks

Hi cpye,

After warming up means the engine rpm is lower as cold engines will have the cold start valves working making the rpm higher.

What about in Reverse? Is it worse?

Is any jerk felt when shifting into Drive or Reverse?

I believe it is the engine mounts that requires attention.

Hi,

There isn't any jerk when shifting into either Drive or Reverse. Also, the vibration is the same in either Drive or Reverse.

A post on this website, about an older Camry, suggested it could be either the EGR or the Idle Air Control. Is that possible?

If it is, should I have my mechanic look into the motor mounts first or the EGR and IAC?

Thanks

Hello, while in Neutral or Park my car idles at approximately 650-700 RPM and I feel no vibration. When I put it in drive, but with my foot still on the brake and the car is NOT in motion the idle speed drops to 550-600 RPM and the car starts vibrating.
Is there any sort of adjustment that I can perform myself without taking it to the shop

Hi cpye,

If the idling speed is below 700 rpm when gears are engaged, then you need to check the IAC and throttle body first.

Should not be the EGR, rpm too low for it to be in operation.

Hi there,

Thank you for the donation,

Please check this first, start the car and pull on the hand brake, have the A/C off and put it into drive, with the foot brake off. What is the idle speed and quality like now?

Sounds more like a vacuum leak on the hose to the brake booster or the booster is leaking. If its happening only when brakes are being applied.

Hi there,

As the last post has mentioned, this will be a way of proving the booster, do this test and a mod will advise on where to go next.

To check the vacuum booster, pump the brake pedal with the engine off until you've bled off all the vacuum from the unit. Then hold the pedal down and start the engine. You should feel the pedal depress slightly as engine vacuum enters the booster and pulls on the diaphragm. No change? Then check the vacuum hose connection and engine vacuum. If okay, the problem is in the booster and the booster needs to be replaced.
